The main steps of DNA replication include initiation, unzipping the DNA strands by helicase, primer binding, elongation where DNA polymerase adds nucleotides, and finally, termination when replication completes. Why is DNA replication considered semi-conservative? DNA replication is semi-conservative because each new DNA molecule consists of one original (template) strand and one newly synthesized strand, preserving half of the original molecule in each new copy. What enzymes are essential for DNA replication and what are their roles? Key enzymes include helicase (unwinds the DNA), DNA polymerase (adds nucleotides to build the new strand), primase (synthesizes RNA primers), and ligase (joins Okazaki fragments on the lagging strand). How does the replication process ensure accuracy in copying DNA? DNA polymerase has proofreading ability, which allows it to detect and correct mismatched nucleotides during replication, ensuring high fidelity in copying genetic information. What is the significance of replication forks in DNA replication? Replication forks are Y-shaped structures where the DNA double helix is unwound to allow replication to occur on both strands simultaneously, speeding up the process. How do Okazaki fragments contribute to DNA replication on the lagging strand? Okazaki fragments are short DNA segments synthesized discontinuously on the lagging strand, which are later joined together by DNA ligase to form a continuous DNA strand.
