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.
There are two different types of nucleic acid polymerases.
DNA-dependent DNA polymerases
DNA-dependent RNA polymerases
The DNA-dependent DNA polymerases use a DNA template for synthesizing a new strand of DNA, whereas DNA-dependent RNA polymerases use a DNA template strand for synthesizing RNA.
(a) Repetitive DNA and satellite DNA
satellite DNA Repetitive DNA
Satellite DNA
Repetitive DNA are DNA sequences that contain small segments, which are repeated many times.
Satellite DNA are DNA sequences that contain highly...
RNA is more labile and prone to degradation (owing to the presence of 2’ OH group in its ribose). Hence heat-killed S-strain may not have retained its ability to transform...
(a) : RNA contains cytosine and uracil as pyrimidine bases while DNA has cytosine and thymine. Both have the same purine bases i.e. guanine and adenine.
