Roles of DNA and RNA in the Human Body and Medicine Anatomy and Physiology 1 Dr. Joy Henry Schonathan Crews 3/20/2015 Roles of DNA and RNA in the Human Body and Medicine Introduction Deoxyribonucleic acid (DNA) is the foreman of the body with a strict set of blueprints for what needs to be done in an organism’s cell and how.1 Each cell is encoded with a specific sequence of DNA which stores how it is to be made and reproduce. Ribonucleic acid (RNA) is the assistant to the foreman

DNA FINGERPRINTING DNA fingerprinting is a method of identification that compares fragments of deoxyribonucleic acid. It is a technique used to distinguish between individuals of the same species by using only samples of their DNA. It is also called DNA typing. DNA is the genetic material found within the cell nuclei of all living things. In mammals‚ the strands of DNA are grouped into structures called chromosomes. Unless dealing with identical twins‚ the complete DNA of each individual is unique

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA stands for Deoxyribonucleic acid and looks like a spiral. The spiral is also known as a double helix. The strands are made up of our genetic information‚ composed of genes and chromosomes. There are four bases divided among purines and pyrimidines. On the purines there are Adenine (A) and Guanine (G). On the pyrimidines there are Cytosine (C) and Thymine (T). The
