What does “semi-discontinuous†DNA replication mean? Explain inwords how the lagging DNA strand is replicated in bacteria. Whatspecific enzymatic activities does DNA polymerase I have? Name eachactivity and explain its role in DNA replication. If DNA polymeraseI lacked its 3’-5’ exonuclease activity, what specific consequenceswith respect to DNA replication would be observed? Whatconsequences would be observed if, instead of DNA pol I, DNApolymerase III lacked its 3’-5’ exonuclease activity? Explain youranswers.
