What is the result when DNA ligase has completed its job?

two new strands of DNA

four all-new strands of DNA

one old and one new strand of DNA

several short strands of DNA

The specific type of enzyme - the DNA ligase that facilitates the joining of DNA strands together by catalyzing the formation of a phosphodiester bond. The DNA ligase seals up the sequence of DNA into two continuous double strands The result when DNA ligase has completed its job is:

two new strands of DNA.

The result is two DNA molecules consisting of one new and one old chain of nucleotides.
