What enzyme connects the new bases to the old bases in the DNA template?

Answer;

Ligase enzyme

Ligase enzyme is the enyzme that connects the new bases to the old bases in the DNA template.

Explanation;

Ligase enzyme plays important roles in the process of DNA replication and DNA repair.

It seals repairs in the DNA, it seals recombination fragments, and it connects Okazaki fragments.

It facilitates the joining together of the DNA strands by catalyzing the formation of phoshodiester bond.

It is the enzyme Polymerase that connects the new bases to the old bases in the DNA template. It does this by using base-pair interactions to determine the sequence.
