2023年6月27日 · Sequencing DNA means determining the order of the four chemical building blocks - called "bases" - that make up the DNA molecule. The sequence tells scientists the kind of genetic information that is carried in a particular DNA segment.
DNA Sequencing - National Human Genome Research Institute
3 天之前 · 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.
DNA Sequencing - National Human Genome Research Institute
2018年4月5日 · To study the exact order (or sequence) of someone's DNA, researchers follow three major steps: (1) purify and copy the DNA; (2) read the sequence; and (3) compare to other sequences.
