Questions & Step-by-Step Solutions

What is the function of primase in DNA replication?
  • Step 1: DNA replication is the process of copying DNA.
  • Step 2: DNA polymerase is the enzyme that builds new DNA strands.
  • Step 3: DNA polymerase cannot start building a new strand on its own; it needs a starting point.
  • Step 4: Primase is an enzyme that makes short pieces of RNA called primers.
  • Step 5: These RNA primers provide the starting point for DNA polymerase.
  • Step 6: Once the primers are in place, DNA polymerase can begin adding DNA nucleotides to create a new strand.
