Recombination Between Two Alu Elements Can Result in Deletions of Chromosome

Multiple Choice

Recombination between two Alu elements can result in deletions of chromosome segments. In a recent study, researchers compared Alu recombination- mediated deletions of humans and chimpanzees. They identified 492 human- specific deletions of this type. Why is this finding important?

A) It shows that humans are not as genetically close to chimpanzees as researchers previously thought.
B) It demonstrates the importance of Alu recombination in shaping genome divergence.
C) It shows how much the chimpanzee genome has changed since the divergence of these two lineages.
D) It shows that the time of divergence of the two lineages is much older than was previously thought.
E) It shows that more deletions have occurred in humans than in chimps.
