WebMar 5, 2024 · All DNA polymerases share two general characteristics: They add nucleotides to the 3'-OH end of a primer. The order of the nucleotides in the nascent polynucleotide is template directed. Figure 1.4.1: DNA Replication. In addition to the 5'->3' polymerase activity, polymerases can contain exonuclease activity. WebPCR is shorthand for a simple but very useful procedure in molecular biology called the polymerase chain reaction. It is a technique used to amplify a segment of DNA of interest or produce lots and lots of copies. In other words, PCR enables you to produce millions of copies of a specific DNA sequence from an initially small sample – sometimes even a …
