Why is there a problem replicating the ends of linear DNA?
Group of answer choices
Leading strand synthesis primed at the replication origin of a linear DNA can’t remove and replace the primer.
Lagging strand synthesis primed at the ends of a linear DNA can’t be removed and replaced because there is no 3'-OH available.
Since replication only initiates at the ends of linear DNA, the priming of each leading strand leaves a primer at the end that cannot be removed.
Primase cannot copy telomere DNA.

Telomeres are long stretches of non-coding DNA at the ends of linear (eukaryotic chromosomes. A beneficial effect of having telomeres is that they -7 speed up the rate of cell proliferation. B)prevent shortening of the leading strand of the DNA during replication prevent shortening of the lagging strand of the DNA during replication D. eliminate the need for RNA primers during DNA replication E. help to splice out introns

Question 1 (0.5 points) Why is there a lagging strand and a leading strand during replication? O Because the helicase unwinds the dna in only one direction. Because DNA polymerase can only add nucleotides to the 3'end of a chain of nucleotides and replication proceeds in both directions. b) c) Because a primer must be laid down first. because DNA polymerase lacks proofreading ability.
