DNA replication and RNA transcription and translation (video)
DNA serves as the molecular basis of heredity through replication, expression, and translation processes. Replication creates identical DNA strands, while transcription converts DNA into messenger RNA (mRNA).
DNA Repair 1 - Khan Academy
DNA polymerase III plays a crucial role in DNA replication, proofreading and correcting errors. It works alongside DNA helicase and other enzymes to ensure accurate replication. When mistakes occur, the mismatch repair mechanism steps in post-replication to fix errors, preventing mutations and maintaining DNA integrity.
Lesson 4: Translation - Khan Academy
DNA serves as the molecular basis of heredity through replication, expression, and translation processes. Replication creates identical DNA strands, while transcription converts DNA into messenger RNA (mRNA).
