Deoxyribonucleic Acid or DNA: Defining Our Life

- Deoxyribonucleic Acid or DNA: Defining Our Life Genetics is defined as the study of heredity. Heredity is controlled by genes, which aid in the development of a cellular organism’s definite characteristics. Such characteristics include sex, hair color, eye color, and countless other traits. Genes are composed of deoxyribonucleic acid, more commonly abbreviated as DNA. Deoxyribonucleic acid carries the genetic material for all cellular organisms. These molecules carry the information needed to direct many important processes that take place inside of the cell....   [tags: Biology Science Research Papers]

DNA: Exploring Creation With Biology

- DNA is the basic substance in the life forms you see around you, yet it is a complicated concept. Your DNA determines the color of your eyes, skin, hair and enable functions such as your sight and hearing. DNA stands for Deoxyribonucleic Acid which contains the biological aspects that make everyone individually different. DNA is all contained in one molecule, and there are millions of tightly packaged DNA cells all throughout many life forms making it the building block of the DNA. In the late 1860’s, a Swiss chemist named Friedrich Miescher first identified DNA....   [tags: Deoxyribonucleic Acid, Scientists, Studies]

DNA

- DNA DNA, or Deoxyribonucleic Acid, is described, in Encarta Encyclopedia as a genetic material of all cellular organisms and most viruses. DNA carries the information needed to direct protein synthesis and replication. Protein synthesis is the production of the proteins needed by the cell or virus for its activities and development. Replication is the process by which DNA copies itself for each descendant cell or virus, passing on the information needed for protein synthesis. In most cellular organisms, DNA is organized on chromosomes located in the nucleus of the cell....   [tags: Deoxyribonucleic Acid essays research papers]

Titration Is A Measured Volume Of Acid

- A titration is used to determine the amount of acid in a given solution. This is done by titrating a measured volume of acid (in this instance, acetic acid (CH3COOH)) with a solution of a strong base (usually sodium hydroxide (NaOH)), of a known concentration. The NaOH is added in small aliquots until the acid has been neutralised, and this can be determined with an indicator dye, such as phenolphthalein, or a pH meter (Nelson & Cox, 2008 pg58). In this practical, a pH meter was used and this allows for the acidity or alkalinity of a solution to be measured, and this was more accurate than using an indicator dye....   [tags: PH, Acid dissociation constant, Acetic acid]

In an acid-base titration an acid neutralizes a base or vice versa. This process is maintained untill the reaction between the titrant and the sample (acid and the base) is judged to be complete. The reaction is judged to be complete when the endpoint is reached.

Sulphuric Acid Production Should Not Be Banned

- ... AB + CD → AD + CB Acids and bases can vary in strength. Their strength is determined by the amount of ionisation when reacted with water. Strong acids & bases are 100 % ionised in water, whereas weak acids & bases are far from 100 % ionisation. There are four types of neutralisation reactions that can occur between strong & weak acids and bases. 1. Strong acid + strong base  Salt + water e.g. HNO3 + LiOH  LiNO3 + H2O In this reaction, the products are always a salt and water. The salt, in a reaction between a strong acid & a strong base, always has a pH of 7.00....   [tags: environmental issues]

Analyzing Citric Acid

- The most widely used method for synthesizing citric acid was discovered by an American chemist named James Currie in 1917 in order to contend with the lack of citrus imports caused by the First World War. This method requires the fungus culture “Aspergillus niger”. This mould is fairly common in nature but special strains are used by the major citric acid producing companies to increase the fungus’s production of citric acid. This method involves substances that contain glucose such as simple sugar or molasses being fed to the fungus....   [tags: Chemistry]

Magnetized Wetlands and Acid Mine Drainage

- Magnetized Wetlands and Acid Mine Drainage Acid mine drainage is a problem that affects many states, specifically being an extremely large problem in Pennsylvania. Target ores often contain sulfides, which react with the air and water to form sulfuric acid. Sulfuric acid, being one of the six strong acids, completely dissociates and dissolves harmful metals in the surrounding rock. These harmful metals include arsenic, copper, iron, etc. The dissolved metals sink to the bottom of ponds, rivers, and streams; this causes acid mine drainage to be a perpetual problem....   [tags: environmental issues, water contamination]

The Utility of Nucleic Acid Hybridisation and Nucleic Acid Probes In Molecular Biology

- The unique property of nucleic acids to pair with each other through complementary base pairing is the lifeblood of genetic engineering. A single strand of DNA can pair up with another strand of DNA or RNA if its base pairs are complementary to those of the other strand, under the right conditions of temperature and pH. This phenomenon is called nucleic acid hybridisation. It is possible to exploit this mechanism for the detection of one nucleic acid strand from a mixture of many other strands....   [tags: Molecular Biology]

In step two, the methyl substituent on p-acetotoluidide was oxidized to produce p-acetamidobenzoic acid. In step three, p-acetamidobenzoic acid was hydrolyzed to remove the protecting group to produce p-aminobenzoic acid. In step four, p-aminobenzoic acid was esterified to produce benzocaine.
