Question

Dependingupon the chemical nature of the template (DNA or RNA) and the natureof nucleic acids synthesised from it (DNA or RNA), list the types ofnucleic acid polymerases.

Answer 1

Thereare two different types of nucleic acid polymerases.

(1) DNA-dependent DNA polymerases

(2) DNA-dependent RNA polymerases

TheDNA-dependent DNA polymerases use a DNA template for synthesizing anew strand of DNA, whereas DNA-dependent RNA polymerases use a DNAtemplate strand for synthesizing RNA.
