Understanding Nucleotides and DNA Study Guide

This guide explains the fundamental biological process of DNA replication. It covers the essential enzymes involved, such as DNA polymerase, helicase, primase, topoisomerase, and single-strand binding proteins. The guide details the stages of replication, including initiation at the origin of replication, the formation of replication forks, and the distinct mechanisms for synthesizing the leading and lagging strands. It also addresses the management of torsional strain and supercoiling by topois
