Explanation:
Detailed explanation-1: -RecBCD binds to the ends of a double stranded DNA break and initiates unwinding of the duplex using its ATP-dependent helicase activity. RecBCD also contains a single stranded (ss)DNA exonuclease activity that initially degrades the unwound ssDNA from both the 3’ and 5’ ends.
