Final answer:
DNA polymerase gamma (pol y) is responsible for mitochondrial DNA replication in eukaryotic cells, distinct from the other eukaryotic DNA polymerases such as alpha, beta, delta, and epsilon.
Step-by-step explanation:
In eukaryotes, DNA polymerase gamma (pol y) is involved in mitochondrial DNA replication. Unlike the other DNA polymerases such as pol alpha, pol beta, pol delta, and pol epsilon, which play roles in nuclear DNA replication, DNA pol y is specifically tasked with replicating the mitochondrial DNA, which is essential for the proper functioning of mitochondria. Eukaryotic cells contain several DNA polymerases including pol alpha, pol beta, pol gamma, pol delta, and pol epsilon, which are involved in various aspects of DNA synthesis and repair.
