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. WebDNA replication occurs through the help of several enzymes. These enzymes "unzip" DNA molecules by breaking the hydrogen bonds that hold the two strands together. Each strand then serves as a template for a new complementary strand to be created. Complementary bases attach to one another (A-T and C-G).

PCR relies on a thermostable DNA polymerase, Taq polymerase, and requires DNA primers designed specifically for the DNA region of interest. In PCR, the reaction is repeatedly cycled through a series ...

WebIn conclusion, errors in DNA replication, recombination, or repair can lead to changes in the DNA sequence that can lead to changes in gene expression and the cellular level. These changes can lead to an increased risk of developing CVDs due to an increase in the levels of cholesterol, glucose, and inflammation in the body.
