DNA Definition, Discovery, Function, Bases, Facts,
WebDNA sequencing is the process of determining the sequence of nucleotides (As, Ts, Cs, and Gs) in a piece of DNA. In Sanger sequencing, the target DNA is copied many times, making fragments of different lengths. Fluorescent “chain terminator” nucleotides mark the ends of the fragments and allow the sequence to be determined. Two types of enzymes are used in this method: 1. Restriction enzymes 2. DNA ligase The restriction enzymescut the DNA at specific target sequences. The target gene is inserted into the cut site and is ligated by DNA ligase. This is known as a recombinant plasmid. See more The recombinant plasmid is introduced into bacteria such as E.coli. The bacteria are subjected to very high temperatures which compel them to take up the DNA. This process is known as transformation. The plasmid contains … See more The plasmid-containing bacteria are cultured, and the bacteria are provided with a chemical signal that helps them to target the protein. After protein production, the bacteria are split open to release it. The protein is … See more lich da banh aff
