Keywords to optimize 4 SEO: DNA replication worksheet, DNA replication activities, DNA replication diagram, DNA replication questions, biology practice worksheets, molecular biology exercises, DNA enzyme functions, genetic process worksheets, DNA replication study guide, biology exam preparation QuestionAnswer What are the main steps involved in DNA replication? The main steps are initiation, unwinding the DNA strands, primer binding, DNA synthesis by DNA polymerase, and termination. This process ensures each new cell receives an identical copy of DNA. Why is DNA replication considered semi-conservative? Because each new DNA molecule consists of one original (template) strand and one newly synthesized strand, conserving half of the original DNA in each copy. What enzymes are essential for DNA replication? Key enzymes include DNA helicase (unwinds the DNA), DNA polymerase (synthesizes the new strands), primase (lays down RNA primers), and ligase (joins Okazaki fragments). How does replication ensure high fidelity and reduce errors? DNA polymerase has proofreading activity that detects and corrects mismatched nucleotides during replication, ensuring high accuracy in copying genetic information. What is the significance of replication origins in DNA replication? Replication origins are specific sequences where DNA replication begins, allowing the process to start simultaneously at multiple sites, speeding up the overall replication process. How do leading and lagging strands differ during DNA replication? The leading strand is synthesized continuously in the 5' to 3' direction, while the lagging strand is synthesized discontinuously in Okazaki fragments, which are later joined together.
