The natural function of 3\' ->5\' exonuclease activity of a DNA polymerase is to:

please choose correct answer. thank you!

The natural function of 3 5\' exonuclease activity of a DNA polymerase is to Select one: a. Remove the 5\' end of the DNA strand that is being copied b. Remove damaged nucleotide from the template strand X C. Remove nucleotides from the end of DNA to generate blunt ends d. Remove incorrect nucleotides from the newly synthesized DNA

Solution

Ans D

The 3\' -5\' exonuclease activity of dna polymerase identifies the incorrect nucleotides from the newly synthesized DNA sequence and excise it.

This property of enzyme is called as proof reading.
