Question: what are two major functions that dna polymerase performs?
Answer: Primary functions of DNA polymerases. DNA polymerases are a group of polymerases that catalyze the synthesis of polydeoxyribonucleotides from mono-deoxyribonucleoside triphosphates (dNTPs), performing the most fundamental functions in vivo of DNA replication, repair, and, in some cases, cell differentiation.
