Question

what property of the dna molecule explains the necessity for okazaki fragments?
○ dna is antiparallel.
○ dna is negatively charged.
○ dna is a linear molecule.
○ dna is wound around histones.

Explanation:

DNA polymerases can only synthesize new DNA strands in the 5' to 3' direction. Since the two strands of DNA run in opposite (antiparallel) directions, the lagging strand must be synthesized in short, discontinuous segments called Okazaki fragments, while the leading strand is synthesized continuously. The other listed properties do not relate to the need for Okazaki fragments.

Answer:

DNA is antiparallel.
