Strawberries
Strawberries are small delicate fruit. They can range from having a cone shape, to a spherical shape. They are red juicy fruits thats seeds grow on the outside. They can average about 200 seeds on them and are the only fruits that have their seeds on their skin. Strawberries are the first fruit to ripen in the spring. Strawberries are part of the rose family and are part of the plantae family. Strawberries can usually prevent heart attacksStrawberries grow on plants that can yield strawberries for more 5 years if its healthy and isn’t attacked by insects. They were thought to get their name when the farmers put straws around them for protection earning the strawberry name. Strawberries also contain 90% water. They grow on low growing plants that grow white flowers that later become strawberries. The main plant can send out runners that can form a new plant and grow more strawberries. Strawberries usually grow 12 weeks after planted. The strawberry plant needs insects to pollinate their flowers. When eaten strawberries can give you vitamin C, iron and other minerals.It contains 18mg potassium and gives people 4 calories. In Italy they were first grown in 234 B.C. The first strawberries were found in Virginia by Europeans in 1588. Then in 1860 framers in America started planting them.But the first strawberries where picked in the forests and in ancient rome was used to make medicine. Strawberries are usually planted using the plasticulture method. This method is when people build large beds of soil and cover them with plastic and adding seeds and making holes so the seed can grow. The plastic will prevent weeds and erosion. In the beds they would implant tubes that export water to the strawberries. Framers pick straw...

...ates. Dish detergent is a thick liquid that can have antibacterial properties. They were made in 1916 when soap was not used as much for cleaning.

Cells
Cells are the things that hold the DNA. Every living organism contains at least one cell. They are sometimes known as the building blocks of life. Cells were discovered in 1839 by Schleiden and Schwann.

The Science Behind the Project
In the project you isolate DNA from strawberries. When you mash the strawberries you get the DNA into a solution. The solution of salt and dish detergent bust open the cells to release the DNA so its easier to get the DNA. When you pour it in the cup you filter the clunks of the strawberries and get the solution and the material that contain the cells. So to separate the DNA you add the alcohol it precipitates. The DNA will fall out of the cells. The DNA can be used to be analyzed.

DNA And DNA : The History Of DNA Essay

- This paper explains the history of DNA, deoxyribonucleic acid, and its twisted or weird history. DNA is a genetic material in our cells that gives us our different traits. It is made of three essential things, which are phosphates, sugars, and nitrogenous bases.There are four types of bases cytosine, guanine, thymine, and adenine. Adenine and guanine are purines meaning that they have two rings. Cytosine and thymine are pyrimidines meaning that they have one ring. Adenine pairing with thymine and guanine pairing with cytosine....   [tags: DNA, Francis Crick, Nucleic acid, RNA, Gene]

Use of DNA in Criminal Investigations Essay examples

- Before the 1980s, courts relied on testimony and eyewitness accounts as a main source of evidence. Notoriously unreliable, these techniques have since faded away to the stunning reliability of DNA forensics. In 1984, British geneticist Alec Jeffreys of the University of Leicester discovered an interesting new marker in the human genome. Most DNA information is the same in every human, but the junk code between genes is unique to every person. Junk DNA used for investigative purposes can be found in blood, saliva, perspiration, sexual fluid, skin tissue, bone marrow, dental pulp, and hair follicles (Butler, 2011)....   [tags: DNA Forensics]

Dna Fingerprinting : Forensic Investigation Essay

- DNA fingerprinting, one of the great discoveries of the late 20th century, has revolutionized forensic investigations. This reviews about 30 years of progress in DNA Fingerprinting analysis which helps to convict criminals, free the wrongly accused, and identify victims of crime, disasters, and war. Current standard methods based on short tandem repeats (STRs) are covered. Advancements and expanding forensic DNA databases are discussed and we ask what the future holds for all types of DNA fingerprinting....   [tags: DNA, DNA profiling, Alec Jeffreys]

Essay Dna Cloning And Genetic Engineering

- DNA cloning and genetic engineering are a vital aspect of the field of genetics. DNA cloning provides the ability to isolate and replicate genes of interest and study their direct impact on organisms. Genetic engineering and transformation provide an insight on an issue of great caliber, the increase of antibiotic resistant bacteria. The extraction and inserting of genetic material are known as miniprep and transformation, respectively. A vector is essential in order to transform genetic material between bacteria....   [tags: DNA, Molecular biology, Bacteria]

Dna, Is It A Done Deal? Essay

- DNA, is it a done deal. A gene is the basic physical and functional unit of heredity. Genes, which are made up of DNA, guide the production of all the necessary components of an organisms cell. Gene determine the features of a cells or the lack of thereof. The genetic material being the crucial part of our inheritance is not an absolute factor that seals our fate. Scientists now refer to the term epigenetic for a more comprehensive understanding of genetics. Epigenetic changes can help determine whether genes are turned on or off and can influence the production of proteins in certain cells, ensuring that only necessary proteins are produced....   [tags: DNA, Genetics, Mutation, Cancer]

Essay on Dn Dna And Dna

- Almost every cell in our body contains deoxyribonucleic acid (DNA). DNA can be defined as “a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms…” (University of Utah, 2014). In other words, DNA is a genetic material that contains the information of how cells work. DNA can be used to identify people because everyone has different DNA sequences and varying lengths of DNA. Every human cell contains 3 billion DNA base pairs. We share about 99.9% of our DNA, but the remaining 0.1% is unique....   [tags: DNA, DNA profiling, Molecular biology]
