DNA analysis. Petri dish with the letters DNA,test tubes and eppendorf tubes containing samples of DNA (deoxyribonucleic acid) on graphs showing the results of DNA sequencing. A DNA molecule consists of two sugar-phosphate backbones,arranged as a double helix,joined by nucleotide bases. There are 4 types of nucleotide base; adenine (A),cytosine (C),guanine (G) and thymine (T). Sequences of these bases make up genes,which encode an organism's genetic information. Uses of DNA sequencing include; finding genes responsible for disease,DNA fingerprinting and paternity testing | |
