Function of DNA ligase -: (A) Cutting of DNA at specific site, (B) Preventing negative supercoil, (C) To seal and nick okazaki fragments, (D) DNA polymerization
Answer is C. Ans. is 'c' i.e., To seal and nick okazaki fragments ProteinFunctionDNA polymerasesDeoxynucleotide polymerizationHelicasesProcessive unwinding of DNATopoisomerasesRelieve torsional strain that results from helicase-induced unwindingDNA primaseInitiates synthesis of RNA primersSingle-strand binding proteinsPrevent premature reannealling of dsDNADNA ligaseSeals the single strand nick between the nascent chain and Okazaki fragments on lagging strand
