1.	Match the items in Column I with Column II and select the correct option from the codes given below.Column IColumn IIA.DNA ligase1.Endonuclease that digests ss or ds DNAB.DNase I2.Unpackaging DNA strandsC.DNA topoisomerase3.Catalyses the covalent bonds of segments of an interrupted sugar phosphate strand in ds DNAD.DNA helicase4.Produces single or ds breaks in DNA during replication to release tension brought about by DNA uncoilingCodesABCD(a)1234(b)4321(c)3142(d)2413
Answer» The correct matches are given by option (c). DNA ligase joins the ends of DNA segments. It catalyses the covalent bonds of segments of an interrupted sugar phosphate strands in ds DNA. DNase I is an endonuclease that digests ds or ss DNA. DNA topoisomerse relieves torque or strain. DNA helicase unwinds the double helix.
