When a sample such as blood or saliva is obtained, the DNA is only a small part of what is present in the sample. Before the DNA can be analyzed, it must be extracted from the cells and purified. There are many ways this can be accomplished, but all methods follow the same basic procedure. The cell and nuclear membranes need to be broken up to allow the DNA to be free in soluti… 網頁1. isolation of DNA from other cell components 2. digestion of DNA using restriction endonuclease 3. electrophoreses of DNA pieces * separates them by size - smaller pieces travel faster 4. probing of DNA after using southern blot to transfer DNA to a stable membrane support Restriction Endonuclease does what to DNA? * digestion of DNA 網頁DNA 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. parr alco oldham
