Question

1.      . A new organism has recentlybeen discovered. The organism constitutes a new class oforganism with characteristics very similar to eukaryotes. Whenthe DNA replication process was examined, three unique featureswere observed: 1) no primer formation was observe, 2) no Okazakifragments detected, and 3) Shortening of the telomeres wereapparent, but the shortening occurred only at one end of the DNAmolecule/chromosome. Provide a model of DNA replication inthis new organism that is consistent with theseobservations (your response should include characteristics ofthe DNA and mechanisms of replication of that DNA).

Explanation / Answer

Hint: this would be consistent with a single strand of DNA foldedin half
