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

Solution

Depending upon the chemical nature of the template (DNA or RNA) and the nature of nucleic acids synthesised from it (DNA or RNA), there are four  different types of nucleic acid polymerases.
(1) DNA-dependent DNA polymerases. These use DNA as a template for synthesizing a new strand of DNA.
(2) DNA-dependent RNA polymerases. These use a DNA template strand for synthesizing RNA.
(3) RNA-dependent RNA polymerase. These use RNA template synthesize RNA.
(4) RNA-dependent DNA polymerase. These use RNA template to synthesize DNA.
