Question
Order the steps of DNA replication, starting with the first step and ending with the production of a DNA copy.
DNA polymerase adds nucleotides to Partial unwinding of DNA polymerase add nucleotides to the leading strand, which is double-stranded DNA the lagging strand, which is Okazaki fragments are joined synthesized in the 5 3 direction to expose the nucleotides synthesized in the 3 5 direction to form a continuous strand as a continuous strand. on the template strand. as Okazaki fragments. First step Last step The correct ranking cannot be determined.Explanation / Answer
DNA replication is the process of formation of double stranded from a single double-stranded DNA molecule.
?
Partial unwinding of double stranded DNA to expose the nucleotides on the template strand
?
DNA polymerase adds nucleotides to the leading strand which is synthesized in the 5’-3’
direction as a continuous direction.
?
DNA polymerase add nucleotides to the lagging strand which is synthesized in the 3’-5’ direction as Okazaki fragments.
?
Okazaki fragments are joined to form discontinuous strand (not a continuous strand)
?
DNA ligase joins Okazaki fragments and forms a single unified strand.
?
Multiple primers are added to the lagging strand and synthesizes in the 5' to 3' direction on both the leading and lagging strands.
