DNA autoradiogram. Geneticist examining a DNA (deoxyribonucleic acid) autoradiogram. It shows a genetic sequence analysis of DNA samples. The autoradiogram is a visual record of the analysis,created on film by the reaction of small amounts of radioactivity present in each sample. Each band on the autoradiogram represents a nucleotide,the chemical unit that makes up DNA. The ladder of bands has been created by electrophoresis,a technique that separates DNA fragments on the basis of their size. The sequence of nucleotides (adenine,cytosine,guanine,thymine) along a molecule of DNA is known as the genetic code and is unique for every individual | |
