Genetic Testing
Genetic screening uses a variety of laboratory procedures to find out if a person has a genetic condition or disorder or is likely to develop a disease based on his or her genetic makeup. Individuals may wish to be tested if the family shows a history of one specific disease such as Huntington's Disease or breast cancer, if they show symptoms of a genetic disorder which could be improved by early diagnosis, or if they are planning a family and are concerned about the possibility of passing on a genetic trait to their offspring. This last type of screening can look at the parent's genotype or look at the genotype of the fetus or newborn. This type of screening can also look for a specific disorder or can be done as a general test for common disorders as in prenatal testing or more commonly newborn screening.
Genetic tests use techniques to examine genes or markers near the genes. Direct testing for diseases such as Cystic Fibrosis and Sickle Cell Anemia come from an analysis of an individual's specific genes. A technique called linkage analysis, or indirect testing, is used when the gene cannot be directly identified but can be located within a specific region of a chromosome. This testing requires additional DNA from an affected family member for comparison. Because each person's DNA is unique (except for identical twins), genetic tests also can be used for individual identification ("DNA fingerprinting"). This technique is often used in forensic work, where samples from a crime scene such as blood or semen could be used as incriminating or acquitting evidence.
Genetic testing is a complex process, and the results depend both on reliable laboratory procedures and an accurate translation of results. Tests also vary in sensitivity, that is, their ability to detect mutations or to detect all patients who have or will develop the disease. Interpretation of test results are often complex even for trained physicians and other health care specialists.
Types of Genetic Testing
Carrier Identification includes genetic tests used by couples whose families have a history of recessive genetic disorders and who are considering having children. Three common tests include those for cystic fibrosis, Tay-Sachs disease, and sickle-cell trait but more tests are coming on the market at a very high rate. Norman Frost of the University of Wisconsin Madison Medical School says, "Potential new genetic tests roll off the conveyor belt of the human genome project almost once a week " (2).
...ious slaves the right to citizenship, meaning they were able to do anything that a normal citizen could do, for example hold seats of power. The Fifteenth amendment ensured that they were given the right to vote. However, the reason that their accomplishments were in vain was because they did not get rid of racism. Whatever advancement they made was taken back due to whites still believing in racism. After the Reconstruction era, the South feared an African American with power so they formed hate groups and technicalities to get around amendments. Even though the Fourteenth amendment ensured that slaves were given the right to citizenship, the whole ideal of “separate but equal” came into play. With the Fifteenth amendment, the South was able to justify the racist action of enforcing a literacy clause or a grandfather clause by writing it into their constitution.
In Gattaca, the plot focuses on the ethics, the risks, and the emotional impact of genetic testing in the nearby future. The film was released in the 90s; yet in the present, the film does not give the impression of science fiction. Today, genetic testing is prevalent in many aspects of the scientific community. This paper will describe genetic testing, its purpose, diagnostic techniques that use genetic testing, relating Huntington’s disease to genetic testing, and the pros and cons of genetic testing.
Dimmesdale’s confession of his secret sin and embracing it led to his salvation. Reverend Dimmesdale knew that he was at the end of his life and wanted to do God’s will to save himself. What he had to do would be the hardest thing that he had ever done, but he knew that telling the town about his adultery was what he had to do. He came to the pillory, so as to let the town know of his secret sin, and to “make haste to take [his] shame upon [himself],” so as to be redeemed by God (218). Dimmesdale knew that the path he had been taking to redemption was leading him astray. The only he could do to escape the devil, as Chillingworth pointed out when he said, “there was no place…where thou couldst escaped me-save on this very scaffold,” was to own up to his s...
Despite much controversy surrounding the notion of inherited criminal tendencies, there is much evidence to support such theories. Although Lombroso may have employed his theoretic atavisms in an attempt to provide a biologically deterministic method of reducing or preventing crime, they have ultimately lead to an abandonment of gravitas concerning such a notion. However, as myopic as Lombroso's theories of criminality being a hereditary trait appears (Mannheim, 1965) research has shown shared physical characteristics to be commonplace in explicating the argument of genetic criminal behaviour. Although Lombroso presented...
There have been 20 million arrests since 1965 for the possession of marijuana, also known as cannabis. The amount of crime and arrests for possessions of the illicit drug has increased due to the prohibition. Cannabis was a major cash crop for the industrial production prior to its illegalization. It has been estimated that the United States spends approximately $7.7 billion each year to prohibit the use of marijuana alone. Currently the number of people incarcerated is six to ten times higher than European countries (NORML). Today the United States wastes billions of dollars to fight against the war on drugs, for the imprisonment of hundreds of thousands of people, and etc. It’s also brought a raise of violence and crime relating to the dealing and production of the drug. Marijuana should be legalized because its ban has been futile in preventing illicit production, regulating it would allow new development in medical treatments, and would give a boost to the economy. The illegalization of the drug has a much more negative impact then it does well, in fact it’s pushed drug cartels to produce more of the drug because of the high demand and the millions of dollars they’ll make from profits.
When it comes to genetic diseases and conditions, testing can be very helpful and serve a good purpose. People with diseases that are inheritable to their children are encouraged to be tested. For example, in the article about Jewish testing, it says
First, let's consider the situations in which genetic testing would be beneficial to patients. Genetic testing for diseases that are preventable or treatable could allow individuals to alter their lifestyles so as to treat the disease or reduce their risk of developing the disease. For instance, the E2 version of the APOE gene, which is found on chromosome 19, has been linked to heart disease (Ridley, 1999). Individuals who have two copies of the E2 gene are particularly sensitive to high-fat and high-cholesterol diets. Therefore, a genetic test to determine whether a person has the high-risk version of the APOE gene could inform a person of future health risks, thereby allowing the person to change his diet to help prev...
Before we start discussing how genetic tests are developed, let us discuss how genes can trigger disease. A sound body requires the action of many proteins working together. For a protein to function properly, an intact gene must encode for that specific protein. A mutation describes a gene which has been changed. The most common type of mutation is a single change of a nucleotide of DNA. Other types of mutations include the loss or gain of a nucleotide and the disappearance or multiplication of long segments of DNA. Mutations can have three effects: beneficial, harmful, or neutral. Mutations are beneficial if the fitness of an individual is enhanced. Harmful mutations can either slightly alter a protein, where the protein may still minimally function, or they may totally disable a protein. In this instance, the outcome is not only based on how a mutation alters a protein’s function, but on how important the protein is to the body (Understanding Gene Testing).
Nature vs. nurture has been one of the oldest and most debated topics among psychologists over the years. This concept discusses whether a child is born into this world with their developmental work cut out for them or if a child is a “blank slate” and their experiences are what shape them into who they are. Over the years and plenty of research, psychologists have all mostly come to agree that it’s a little bit of both. Children are both born with some genetic predispositions while other aspects of the child’s development are strongly influenced by their surrounding environment. This plays into the criminal justice system when discussing where criminal behavior stems from. Is a criminal’s anti-social behavior just part of their DNA or is it a result of their upbringing? The answer to this question is not definite. Looking at research a strong argument can be made that criminals developed their anti-social patterns through the atmosphere in which they were raise, not their DNA.

When choosing a cat, you should think about if you wan to get a purebred cat from a breeder, or if rescue once from an animal shelter. Are you going to get a kitten or an older cat, also think about certain cats can be trained for special situations. Some cat breeds will have a different temperament than others, but this can vary more for dogs. For an example : Bengal cats are very smart and vocal.They are normally considered high maintains cats. Each cat has their own personality, so you should also interact with them before just taking one home. Also keep in mind daily grooming such as for a longer haired cat they would need to be brushed two-three times a week.
Cats are just as kind, sweet, and loving as any other species of animal which humans can call their pet. The common belief that dogs will give you unconditional love, but cats won't is false. Cats will always love you. They will forgive your mistakes; if you step on their tails, if you lock them in a room for hours, if you don't realize they are in your chair so you sit down on them. They will always come back to your side, ready to be cuddled.
Genetic testing, also known as screening, is a rapidly advancing new scientific field that can potentially revolutionize not only the world of medicine, but many aspects of our lives. Genetic screening is the sequencing of human DNA in order to discover genetic differences, anomalies, or mutations that may prove pathological. As genetic screening becomes more advanced and easily accessible, it presents society with difficult questions that must be asked about the boundaries of science and to what degree we are allowed to tamper with the human genome. To better understand the potential impact of genetic screening on our society, we must examine the potential benefits in comparison to the possible negative impact it may cause. With this knowledge in hand, we can examine what the future holds for this field of study and the best possible direction to take.
Not all European cat breeds are so understated. The Exotic or the Selkirk Rex or the ancient Angora are great examples of this fact. These cat breeds are noted for their striking looks. The Exotic has the body and temperament of a Persian but short dense fur. This cat has been compared to a teddy bear. The Selkirk Rex is one of the few curly haired cat breeds. These are big, solid cats with a lush curled cat. The Angora, one of the oldest cat breeds, is a slightly built cat with a lovely long coat.
There are three types of domestic cats: indoor domestic cats, outdoor domestic cats, and indoor-outdoor domestic cats. Though these cats would look very similar if they were clean and sitting next to each other, they would also be very different.
