Final answer:
The gaps left by missing RNA primers in DNA replication are known as lagging strand gaps or Okazaki fragment gaps, which are filled by DNA nucleotides and sealed by DNA ligase.
Step-by-step explanation:
The gaps left behind by missing RNA primers in DNA replication are known as lagging strand gaps or sometimes referred to as Okazaki fragment gaps.
After the RNA primers are removed, these gaps are filled by DNA nucleotides added by the enzyme DNA polymerase.
Lastly, the enzyme DNA ligase seals these gaps, forming phosphodiester bonds that link the DNA nucleotides, thus completing the DNA strand and ensuring continuity of the DNA molecule.
