DNA EXTRACTION In extracting chromatin from the cells of wheat germ there are seven steps to follow. The optimal cell to use would be the polyploidal eukaryotic. Eukaryotes have nucleus membrane-bound organelles‚ while prokaryotic does not. The polyploidal eukaryotic cell has DNA that is held in the nucleus while the prokaryote has DNA that floats freely around the cell. The DNA of eukaryotes is more complex and extensive than the other. Prokaryote is a bacterial cell that

The Advantages of DNA Replication DNA stands for Deoxyribonucleic acid‚ and it is found in the nucleus of every cell in the human body. DNA is the master plan - it contains all the genetic information needed for a living thing to develop and function. Each and every single organism has a unique and different DNA encoding. DNA’s purpose is to store all of our genetic information similar to the way a builders blue print sets out the design of a house. Without DNA there would be no such thing as

DNA Deoxyribonucleic acid DNA Deoxyribonucleic acid DNA is a nucleic acid that is basis of genetic information. It is like a set of instructions for our bodies and genetic codes. DNA has many different components that make it up such as hydrogen‚ oxygen‚ nitrogen‚ and phospurous. The structure has two long polymers of a simple unit called nucleotides. Holding the back of the structure is sugar and phosphate which are attached by ester bonds. Bonded to each sugar is 4 different types

Extracting DNA from Bananas In the Lab: Extracting DNA from Bananas‚ DNA was removed from bananas that had been blended with water in order to examine how DNA is seen from the naked eye. DNA stands for deoxyribonucleic acid‚ which is a nucleic acid that contains the sugar deoxyribose. DNA is made up of a series of monomers called nucleotides. Each nucleotide has three parts: a deoxyribose molecule‚ a phosphate group‚ and a nitrogenous base. In addition‚ there are four kinds of nitrogenous

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. * * There has been a major effort in the history of science to figure out the structure of DNA. Having a double standard helix DNA has a uniform a diameter in its entire length. The helixes fit within a defined three dimensional space because they are both right handed. Polynucleotide chains are held together by the bases in the (center) hydrogen bonding

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

have made the use of DNA in forensic science possible. In the past twenty years specifically‚ there have been many extraordinary discoveries in the fields of science that have led to the advancement of procedures in forensics. Before DNA testing‚ the most accurate way of identifying people was to match the blood types of suspects with blood found at the scene of the crime. Considering the lack of variability of this procedure‚ it is no surprise just how important the use of DNA in forensics has become
