Explanation:
Detailed explanation-1: -The first nucleotide polymerizing enzyme, DNA polymerase, was discovered in 1957. The free nucleotides that serve as substrates for this enzyme were found to be deoxyribonucleoside triphosphates, and their polymerization into DNA required a single-stranded DNA template.
Detailed explanation-2: -The enzyme that digests DNA in macrophage lysosomes is deoxyribonuclease II (DNase II), also called DNase II or acid DNase, which has the optimal pH at acid condition (Evans and Aguilera 2003).
