WebNov 15, 2024 · ShiningHalley Answer: The enzyme Topoisomerase functions to prevent super-coiling of the DNA molecule during replication. Explanation: During replication, … DNA supercoiling refers to the amount of twist in a particular DNA strand, which determines the amount of strain on it. A given strand may be "positively supercoiled" or "negatively supercoiled" (more or less tightly wound). The amount of a strand’s supercoiling affects a number of biological processes, such as compacting DNA and regulating access to the genetic code (which strongly affects DNA metabolism and possibly gene expression). Certain enzymes, such as topoisomerases, …
