Question

1. label:

original dna dna polymerase ligase leading strand
okazaki fragments lagging strand

Explanation:

• Original DNA (A): The double - stranded DNA before replication begins.
• DNA polymerase (B): Enzyme that synthesizes new DNA strands by adding nucleotides.
• Ligase (C): Enzyme that joins Okazaki fragments on the lagging strand.
• Leading Strand (D): Synthesized continuously in the 5' - 3' direction.
• Okazaki fragments (E): Short fragments on the lagging strand.
• Lagging strand (F): Synthesized discontinuously in the 5' - 3' direction as Okazaki fragments.

Answer:

A. Original DNA, B. DNA polymerase, C. Ligase, D. Leading Strand, E. Okazaki fragments, F. Lagging strand.
