Function of polymerase enzyme
WebRNA polymerase (DNA-directed RNA polymerase) is an enzyme that synthesizes RNA from a DNA template. The synthesis of RNA requires DNA as a template, ensuring that … WebA An overview of the bacterial multi-subunit RNA polymerase. In bacteria, RNA polymerase exists in two states. One form, known as the core enzyme, can catalyze RNA synthesis but is unable to bind to promoter targets in DNA. The second form of RNA polymerase, the holoenzyme, is capable of both RNA synthesis and promoter recognition.

WebPolymerase Function Replication of genomic DNA is the primary function of DNA polymerases. Once the DNA is duplicated accurately, the cell can undergo division with … WebThe function of DNA polymerases is to synthesize complementary strands during DNA replication. DNA polymerases require a primer to provide a free 3′ hydroxyl group for initiation of synthesis. The primers used for most in vitro polymerization reactions are single-stranded DNAs, typically 6 to 20 bases in length, called oligonucleotides.
