What is the definition of DNA polymerase in biology?

DNA polymerase (DNAP) is a type of enzyme that is responsible for forming new copies of DNA, in the form of nucleic acid molecules. Nucleic acids are polymers, which are large molecules made up of smaller, repeating units that are chemically connected to one another.

What is the job of DNA polymerase 1?

Catalyzes the Template-Directed Polymerization of Nucleotides into Duplex DNA in a 5´→3´ Direction. DNA Polymerase I catalyzes the template-directed polymerization of nucleotides into duplex DNA in a 5´→3´ direction.

Why is RNA polymerase slower than DNA polymerase?

RNA polymerase in a nutshell: It synthesises single-stranded RNA during the transcription process. Hence the error rate of the RNA polymerase is much higher than the DNA polymerase. The RNA polymerase is slow, inefficient and adds nucleotides 40 to 50 per seconds.

How is RNA different from DNA?

There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

What is the main function of RNA polymerase?

RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription.
