Which reaction in DNA replication is catalysed by DNA ligase?Group of answer choicesBase pairing of the template to the newly synthesised strandFormation of a phosphodiester linkage between two Okazaki fragmentsProof reading the template strand for errorsAddition of nucleotides to the lagging strand

During DNA replication:Ligase replaces RNA primers with DNA nucleotides.DNA polymerase III pairs Guanine with Cytosine.DNA polymerase I pairs Adenine with Cytosine.Okazaki fragments are created on the leading strand.

Which is true during DNA replication?Group of answer choicesDNA ligase is the last step of the polymerisation reaction for the lagging strand, but is not used on the leading strand.DnaA binds to regions that are rich in AT as this purine-purine base pairing forms only two hydrogen bonds.The β sliding clamp prevents the dissociation of DNA polymerase III, increasing the length of DNA each polymerase can synthesise.DNA gyrase binds to and applies tension to the lagging strand.

Many segments of these are joined together to make up the lagging strand of newly synthesized DNA.Group of answer choicesprimerOkazaki fragmenttelomereorigin of replicationNext

Which is true during DNA replication?Group of answer choicesDNA ligase replaces the nucleotides in the RNA primer with DNA on the newly synthesised strands.RNA primers bound to both the leading and lagging strand are degraded by 5' - 3' exonucleases.DNA polymerase III synthesises the leading strand and DNA polymerase I synthesises the lagging strandPrimase is required to make primers on the lagging strand only
