Questions & Step-by-Step Solutions

Which of the following is required to initiate DNA replication?
  • Step 1: Understand that DNA replication is the process of copying DNA.
  • Step 2: Know that DNA polymerase is the enzyme that builds new DNA strands.
  • Step 3: Realize that DNA polymerase cannot start building a new strand on its own.
  • Step 4: Learn that an RNA primer is a short piece of RNA that provides a starting point.
  • Step 5: Conclude that the RNA primer is necessary for DNA polymerase to begin synthesizing new DNA.
