DNA is a double helix molecule that contains information that is used to make up a person’s body. DNA controls every aspect of a person’s body from their eye and hair color‚ height‚ and other features. DNA’s specific and unique characteristic can be crucial when solving a crime. DNA can be used to convict a suspect or exonerate an innocent person. When DNA is found it is even more important that is handle properly to ensure proper identification and accuracy of testing.

DNA Extraction Lab Problem Statement: Do you think you have ever eaten DNA? Background Information: DNA is too small to see under a regular microscope‚ so how can it be studied? DNA is a large molecule found in all living things; therefore it is possible to extract it from cells or tissues. All we need to do is disrupt the cell’s plasma membrane and nuclear envelope‚ make the DNA clump together and - voila! - DNA extraction is possible. DNA extractions from onion‚ bananas‚ liver‚ or wheat

RECOMBINANT DNA TECHNOLOGY * It is a technology that allows DNA to be produced via artificial means. * It is the joining together of DNA molecules from two different species that are inserted into a host organism to produce new genetic combinations that are of value to science‚ medicine‚ agriculture‚ and industry. * Since the focus of all genetics is the gene‚ the fundamental goal of laboratory geneticists is to isolate‚ characterize‚ and manipulate genes. Although it is relatively

Strawberry DNA lab Extraction Purpose: The purpose of this lab experiment is to see if this particular type of fruit which in this case is a strawberry contains DNA. Using materials such as a Ziploc bag to help keep the entire strawberry in one place while it gets smashed and test tube to help better see the DNA and break down of the liquid in the left over strawberry sediments. Background information: The long thick fibers of DNA store the information for the function of the chemistry

When DNA profiling was first used in criminal cases‚ it was often difficult for prosecutors and defense attorneys‚ as well as the experts they hired to testify‚ to explain the significance of their DNA match to the jury. Fingerprints are still considered by most people to be an ironclad way to identify someone‚ but an expert testifying about fingerprints discusses them in terms of "points of similarity." DNA matches are discussed in terms of statistical probability using what is currently known about

procedure for extracting DNA‚ collecting DNA samples‚ and to observe the physical characteristics of DNA Background: The wild strawberry is a diploid because it only has two sets of chromosomes. While the grocery store kind is an octoploidy because it has eight sets of chromosomes. The reason we chose the grocery store strawberry is because we’d be able to extract more DNA. Ripe strawberries make enzymes which help break down the cell walls making it easier to extract the DNA. We will be using a solution
