Please ell with study guide 6-9 6. Circle ALL the enzyme(s) listed below that catalyze phosphodiester bond formation DNA Ligase DNA polymerase I DNA polymerase lIll Endonuclease Exonuclease Helicase Primase Telomerase Topoisomerase 7. Among the enzymes listed above that catalyze phosphodiester bond formation which one can be classified as an RNA-dependent DNA polymerase? 8. Among the enzymes listed above that catalyze phosphodiester bond formation which one not require a nucleoside triphosphate as a substrate? 9. Among the enzymes listed above that catalyze phosphodiester bond formation which one does not require a pre-existing chain?Explanation / Answer
Ans 6) Enzyme responsible for the formation of phosphodiester bond are:-
DNA ligase, DNA Polymerase I, DNA Polymerase III. Telomerse, Primase
Ans 7) Telomerse enzyme is responsible for the formation of RNA dependend DNA polymerase activity.
Ans 8) DNA ligase, primase does not require nucleotide triphosphate for the formation of phosphodiester bond.
Explain:- DNA ligase joins the two unliked nucleotide by forming a phosphodiester bond.
Ans 9)DNA ligase and Primae does not require pre-existing chain for the formation of phosphodiester bond.
Explain:- DNA ligase works by th joiing a nick in the Nucleotide strand. Primase add the bucloeotide independenlt to for small RNA primer.
