Why is RNA primer required for DNA replication?
Understand the Problem
The question is asking about the role of RNA primers in the process of DNA replication, specifically why they are necessary for this biological process.
Answer
RNA primers are necessary for DNA polymerase to start DNA replication.
The final answer is that an RNA primer is necessary because DNA polymerase requires an existing nucleotide chain to begin adding nucleotides.
Answer for screen readers
The final answer is that an RNA primer is necessary because DNA polymerase requires an existing nucleotide chain to begin adding nucleotides.
More Information
DNA polymerase can only extend an existing chain of nucleotides, making the RNA primer crucial for the initiation of DNA replication.
Tips
A common mistake is thinking that DNA polymerase can start synthesizing DNA from scratch. This is incorrect; it needs a primer to begin.
