The Eukaryotic cells have five several DNA polymerases; α, β, γ, δ or ε. The DNA polymerases contained in replication of chromosomal DNA are α and δ. DNA polymerases β or ε are contained in DNA repair. Overall of these polymerases except DNA polymerase γ are situated in the nucleus; DNA polymerase γ is found replicates mitochondrial DNA and in mitochondria.
