What is the chemical difference between the groups joined byDNA polymerase and D

Question

What is the chemical difference between the groups joined byDNA polymerase and DNA ligase? a)What are the three enzymatic activities of DNA polymeraseI?    i) The major activity is the one that givesthe enzyme its name.    ii) The second acitivity is the reverse ofthe first.    iii) The third activity is similar to ii butis unique to DNA pol I.

Explanation / Answer

DNA Polymerase forms a sugar-phosphate bond between the nucleotidesin a new DNA chain. DNA poly catalyzes the polmerizationreaction that integrates the new nucleottides at the primerterminus when the correct base pair is presented. DNA ligase joins the sticky (complementary) ends of cleavage sitesfrom overhangs that make double stranded DNA from singlestranded. It's an enzyme that polymerizes deoxyribonucleic acids It proofreads strands It participates in DNA repair processes
