Question

Eukaryotic telomeres replicate differently than the rest of the chromosome. This is a consequence of which of the following?

A) The evolution of telomerase enzyme
B) DNA polymerase that cannot replicate the leading strand template to its 5' end
C) Gaps left at the 5' end of the lagging strand because of the need for a 3' onto which nucleotides can attach
D) Gaps left at the 3' end of the lagging strand because of the need for a primer
E) The "no ends" of a circular chromosome

Answer 1

The correct option is C: Gaps left at the 5' end of the lagging strand because of the need for a 3' onto which nucleotides can attach.

Step-by-step explanation:

To avert any loss of genes due to the wearing down of chromosome ends, the tips of eukaryotic chromosomes have telomeres. These are specialized DNA caps consisting of thousands of replications of the same short DNA sequence. Telomeres are not the same in organisms, but in mammals and humans, they are 5'-TTAGGG-3', and this allows them to replicate than the rest of the chromosome.
