What is the function of a primer?
Understand the Problem
The question is asking about the role and purpose of a primer, which is likely related to biology or chemistry, particularly in processes like DNA amplification or polymerase chain reaction (PCR).
Answer
To provide a starting point for DNA synthesis.
The main function of a primer is to provide a starting point for DNA synthesis by binding to a single-stranded DNA template, allowing DNA polymerase to initiate replication.
Answer for screen readers
The main function of a primer is to provide a starting point for DNA synthesis by binding to a single-stranded DNA template, allowing DNA polymerase to initiate replication.
More Information
In DNA replication, primers are typically short RNA sequences that help DNA polymerases to start the synthesis of the new DNA strand. Without primers, DNA polymerases cannot begin replication, which makes primers essential for DNA synthesis.
Tips
A common mistake is confusing primers used in DNA replication with those used in PCR. Both function similarly but are applied in different contexts.
