MCQ ON DNA REPLICATION is useful for NEET / CSIR / UGC / CBSE / ICSE / AIIMS / EXAM / AFMC EXAM / STATE LEVEL MEDICAL EXAM 2022-23, 2023-24
Introduction:
DNA is a long polymer of deoxyribonucleotides.The length of DNA is usually defined as the number of nucleotides present in it.This also is the characteristics of an organisms.DNA acts as a genetic materials in most of the organisms. DNA replication main enzyme is DNA dependent DNA polymerase, since it uses a DNA template to catalyse the polymerisation of deoxyribonucleotides.These enzyme are highly efficient enzyme.
