Answer:
The correct answer is DNA polymerase 1 helps in primer removal of primer and replacement of covalently links breaks in the sugar phosphate backbone.
Explanation:
DNA polymerase 1 is an important enzyme of DNA replication.DNA polymerase 1 can helps in the attachment of nucleotides in both 3prime to 5prime direction as well as 5 prime to 3prime direction of newly synthesized DNA strand.
DNA plymerase 1 by its 5prime to 3prime exonuclease activity remove the RNA primer from the Template DNA strand and replace the covalently links breaks with appropriate nucleotides .
