Vedclass · Answer

$(B)$ Ligases are enzymes that act as 'molecular glue' by catalyzing the formation of phosphodiester bonds between the $3'-OH$ end of one $DNA$ fragment and the $5'-phosphate$ end of another, thereby joining two $DNA$ molecules together. Exonucleases remove nucleotides from the ends of $DNA$, whereas endonucleases make cuts at specific positions within $DNA$. Polymerases are involved in the synthesis of $DNA$ strands, not in breaking them.
