Recombination Between Two Alu Elements Results in Deletions

question 51

Multiple Choice

Recombination between two Alu elements results in deletions. In humans these have often been associated with specific disorders. 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 shows how much the chimpanzee genome has changed since the divergence of these two lineages.
• C)It shows that the time of divergence of the two lineages is much older than was previously thought.
• D)It shows that more deletions have occurred in humans than in chimps.
• E)It demonstrates the importance of Alu recombination in shaping genome divergence.
