Osmosis video - DNA replication

DNA replication is the process by which a DNA molecule is copied into two identical DNA molecules. This process is essential to ensure the accurate transmission of genetic information from one generation to the next.

DNA replication occurs in three main steps: initiation, elongation, and termination. Initiation involves the unwinding of the DNA molecule, and it happens thanks to DNA helicase and topoisomerase enzymes. Next, elongation consists of making RNA primers by RNA primase and synthesizing the DNA leading strand by DNA polymerase. In termination, converging replication forks meet, and the whole process is complete.
