The work of bacterial proteins in DNA cleavage is to describe the sequence of bases which are present at the sticky ends of the cleaved which has double strand of DNA.
DNA cleavage is termed as the reaction where serves one of the covalent sugar- phosphate linkage which is between nucleotides.
It is being catalyzed, chemically, enzymatically or radiation.
DNA cleavage can be exonucleolytic which means it removes the end nucleotide by splitting it into two parts.
