Expert Solution & Answer

Answer to Problem 1P

The activating intermediate present in the linkage of the enzymes, DNA polymerase I, DNA ligase and topoisomerase I are deoxynucleotide triphosphate, DNA adenylate and DNA-tyrosyl intermediate respectively. The leaving groups present in the enzymes, DNA polymerase I, DNA ligase and topoisomerase I are pyrophosphate, AMP and DNA- tyrosine residue respectively.

Explanation of Solution

It is given that the enzymes, DNA polymerase I, DNA ligase and topoisomerase I help in catalyzing the formation of phosphodiaster bonds.

The activated intermediate present in case of DNA polymerase I is deoxynucleotide triphosphate and the leaving group present in this enzyme is pyrophosphate.

The activated intermediate present in case of DNA ligase is DNA adenylate, in which AMP is attached to 5' phosphate and the leaving group present in this enzyme is adenosine monophosphate(AMP).

The activated intermediate present in case of topoisomerase I is DNA-tyrosyl intermediate, in which 5' phosphate is attached to phenolic −OH group and the leaving group present in this enzyme is the tyrosine residue.
