The lagging strand is characterized by a series of short segments of dna (okazaki fragments) that will be joined together to form a finished lagging strand. the experiments that led to the discovery of okazaki fragments gave evidence for which of the following ideas?
a) dna polymerase is a directional enzyme that synthesizes leading and lagging strands during replication.
b) dna is a polymer consisting of four monomers: adenine, thymine, guanine, and cytosine.
c) dna is the genetic material.
d) bacterial replication is fundamentally different from eukaryotic replication. the key shouldn’t be way longer than the distractors.

A) DNA polymerase is a directional enzyme that synthesizes leading and lagging strands during replication

Explanation:

DNA polymerase add nucleotide during DNA replication and move in the opposite direction on both DNA strands as the two DNA strands are anti-parallel and DNA polymerase add nucleotides from 5 to 3 directions.

The DNA polymerase will move towards the replication fork on one strand. On this strand called the leading strand, DNA polymerase will continually add nucleotide.

The DNA polymerase will move opposite the replication fork on another strand. DNA polymerase copies on this strand called Lagging strand in a discontinuous fashion, so this means series of short fragments or okazaki fragments.  Synthesizing the lagging strand as coping is discontinuous and subsequently linked together.

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.
