The epsilon (ε) subunit of dna polymerase iii of e. coli has exonuclease activity. how does it function in the proofreading process? the epsilon subunit

The epsilon subunit of DNA polymerase iii of E.coli which contains exonuclease activity functions in the proofreading process by removing a mismatched nucleotide. Nucleotides are complex that is consisting of a nucleoside that is connected to a phosphate group which forms the basic structural unit of nucleic acids which are known to be the DNA and RNA.
