Conclusions of DH5α DNA transformation with red colonies resistance to ampicillin and the lacZ gene Introduction: In this experiment‚ a plasmid with a gene that has resistance to the antibiotic ampicillin and has lacZ is used to transfer the resistance into E. coli bacteria in red colonies. This same technique is used to give diabetics their insulin‚ and to give dwarfs growth hormones. The point of this lab is to give the groups an idea how DNA can be transformed

DNA Lab Report SungYong Jang What is DNA? What do the letters stand for? What is it composed of? Where is it found? What is it shaped like? Answer in full sentences. It is the genetic material that can be passed on from parent to offspring DNA --> Deoxyribonucleic acid It composed of Deoxyribose (5 carbon sugar)‚ a phosphate and a Nitrogonous base (the 4 N-bases are Guanine‚ Cytosine‚ Adenine and Thymine) It is a double helix (looks like

EXTRACTING AND PURIFYING GENOMIC DNA FROM A RAT LIVER FOR ELECTROPHORESIS Deoxyribonucleic acid (DNA) is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. Along with RNA and proteins‚ DNA is one of the three major macromolecules essential for all known forms of life. Genomic DNA is the DNA that holds the complete set of genetic data for an organism. In humans‚ the genomic DNA spans 46 chromosomes‚ providing a complete

DNA Extraction of a Musa acuminata Biology Lab Report \Analyze and Interpret A number of steps are required to isolate DNA from cellular contents. Describe what happens at each step‚ and why it acts to separate the parts of the cell. /6 There are three specific steps required to isolate DNA from its cellular contents. The steps used to remove and expose DNA from its cell are: breaking down the food type you are using by crushing it‚ for example a banana or strawberries‚ exposing the substance

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

Objective: The purpose of this lab is to allow you to become familiar with a 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

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

Ballistic Fingerprinting is a method that is used to identify a bullets origin of fire‚ in other words‚ what gun fired the bullet in question. “The technology behind the achievement is called IBIS‚ short for Integrated Ballistics Identification System. Like many ideas in law enforcement‚ including fingerprinting itself‚ IBIS immigrated to the United States. Created by Forensic Technology Inc. of Montreal in 1991

The protein concentration in bovine cells was measured by diluting the homogenate with a 1:5 ratio; 50 microliters of homogenate and 200 microliters of water. Then 5 known protein concentration samples which were 0.4‚ 0.8‚ 1.2‚ 1.6‚ 2.0 mg/ml of bovine serum were used to
