Beta, DNA replication begins with helicase unwinding the DNA, then primase lays down RNA primers. The leading strand synthesizes smoothly, while the lagging strand forms Okazaki fragments, later joined. Proofreading enzymes fix mistakes, but in my medical studies, I see genetic disorders like thalassemia arise when replication errors slip through—books claim perfection, but my patients' stories show otherwise. Khayal rakhna.
