What is the mechanism of nucleic acid biosynthesis, specifically the replication of DNA proposed by Watson and Crick?
Understand the Problem
The question is likely asking about the mechanism of nucleic acid biosynthesis, specifically the replication of DNA as proposed by Watson and Crick. It aims to clarify the process and understanding of DNA replication, highlighting the semiconservative model and its significance in genetics.
Answer
Semiconservative replication.
The mechanism proposed by Watson and Crick is the semiconservative model, where each DNA strand serves as a template for a new strand, resulting in two identical DNA molecules, each with one original and one new strand.
Answer for screen readers
The mechanism proposed by Watson and Crick is the semiconservative model, where each DNA strand serves as a template for a new strand, resulting in two identical DNA molecules, each with one original and one new strand.
More Information
Watson and Crick's semiconservative model contrasted with other models such as the conservative and dispersive models. It was later confirmed experimentally by the Meselson-Stahl experiment.
Tips
Ensure clarity between the different models of replication: semiconservative, conservative, and dispersive.
