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? 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? dna polymerase is a directional enzyme that synthesizes leading and lagging strands during replication. dna is the genetic material. dna is a polymer consisting of four monomers: adenine, thymine, guanine, and cytosine. bacterial replication is fundamentally different from eukaryotic replication.

The correct answer is: DNA polymerase is a directional enzyme that synthesizes leading and lagging strands during replication

DNA polymerase is an enzyme that synthesizes DNA during the DNA replication by adds nucleotides to the 3’ end of a primer. This means that the new chain is formed in a 5’ → 3’ direction.

Because double-stranded DNA is antiparallel, DNA polymerase moves in opposite directions on the two strands-leading and lagging strand. The leading strand is copied continuously since DNA polymerase is moving towards the replication fork.  The lagging strand is copied discontinuous. DNA polymerase is moving away from the replication fork (and helicase that separates the strands), so it must constantly return to copy newly separated stretches of DNA. So,  the lagging strand is copied as a series of short fragments-Okazaki fragments that are joined together by a combination of DNA pol I and DNA ligase.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
