Question -Mutation of subunit epsilon (ε ) of DNA polymerase lll will result in an E. coli strain that has a higher mutation ate Ths is because mutation of subunit ε will affect Select one 5 to 3' exonuclease activity of DNA polymerase lll 5' to 3' DNA polymerase activity of DNA polymerase lll 3' to 5' exonuclease activity of DNA polymerase lll 3' to 5' DNA polymerase activity of DNA polymerase lll Answer - The DNA polymerase IlI helps in replicative DNA synthesis in the E. coli. The Epsilon (ε) subunit is very important for the DNA pol lII, activity. The major function of the ε subunit is 3' to 5' directed exonuclease activity. And also helps in proof reading. when this ε subunit get mutated, it will affect the 3' to 5' exonuclease activity of ONA polymerase IlI. So option (c) is correct. And the & subunit is coded by DNA gene. This helps to remove the incorrectly placed bases . other options are not the correct answer. the exconuclease will helps to remove the bases from the ends of the DNA strand. when ε subunit get mutated, then the wrongly incorporated bases will not get removed. And this increases the mutation rate. So option (c.) is correct option
