Dot Hybridization - an overview ScienceDirect Topics

WebHybridization can be used to classify the DNAs of various organisms. For example, human DNA is 98 percent identical to that of chimpanzees, and these two DNAs form a duplex under stringent conditions. Related sequences of humans and birds can also form hybrids, but only at a much lower stringency. Previous DNA and Information WebThis increases the stringency of the hybridization, given that mismatches will fall apart at lower temperatures. However, too high a temperature will lead to very slow annealing. …
