DNA stands for deoxyribonucleic acid, it is usually an acid that contains genes that help living organisms in development and functions, the DNA has four molecules which are referred to as bases, these bases have a sequence where information is stored, the information contained is retrieved using genetic codes and these codes are retrieved by copying the DNA into related nucleic acid in a process called transcription.
The molecule of DNA is one long chain but it is made up of only four different molecules referred to as bases and they include Cytosine, Adenine, Thymine and Guanine, these molecules make pairs and the DNA in a human cell has 23 pairs where one pair comes from the mother of the person in consideration and the other comes from the father, every persons DNA is unique except for identical twins.
Some uses of the DNA technology include agricultural engineering whereby we have genetically modified food, finger printing and the collection of historical information in history and also anthropology. In this case we will consider finger printing which is useful in crime detection and solving crime.
Scientist will use body products or body parts to detect the perpetrators of crimes, this include blood ...Show more
