BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The enzymes that perform transcription are called RNA polymerases. Like the DNA polymerase that catalyzes DNA replication (discussed in Chapter 5), RNA polymerases catalyze the formation of the phosphodiester bonds that link the nucleotides together to form a linear chain.

Detailed explanation-2: -RNA Polymerase, abbreviated as RNA Pol or RNAP, is an enzyme in molecular biology that synthesises RNA from a DNA template. During the process of transcription, RNA polymerase copies the sequence of DNA into an RNA sequence with the help of the enzyme helicase that opens up the wounded DNA strands.

Detailed explanation-3: -In molecular biology, RNA polymerase (abbreviated RNAP or RNApol), or more specifically DNA-directed/dependent RNA polymerase (DdRP), is an enzyme that catalyzes the chemical reactions that synthesize RNA from a DNA template.

Detailed explanation-4: -Transcription is carried out by an enzyme called RNA polymerase and a number of accessory proteins called transcription factors. Transcription factors can bind to specific DNA sequences called enhancer and promoter sequences in order to recruit RNA polymerase to an appropriate transcription site.

Detailed explanation-5: -RNA polymerases are enzymes that transcribe DNA into RNA. Using a DNA template, RNA polymerase builds a new RNA molecule through base pairing. For instance, if there is a G in the DNA template, RNA polymerase will add a C to the new, growing RNA strand.
