WebApr 10, 2024 · Definition. 00:00. …. DNA sequencing refers to the general laboratory technique for determining the exact sequence of nucleotides, or bases, in a DNA molecule. The sequence of the bases (often referred to by the first letters of their chemical names: A, T, C, and G) encodes the biological information that cells use to develop and operate. WebGenes come in different versions, or alleles. A dominantallele hides a recessiveallele and determines the organism's appearance. When an organism makes gametes, each gamete receives just one gene copy, which is selected randomly. This is known as the law of segregation.
