Question 1
Previously unidentifiable microorganisms have now been identified through ________.
◦ proteomics
◦ transcriptomics
◦ metagenomics
◦ evolutionary genomics
◦ reverse transcription
Question 2
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?
◦ It shows that humans are not as genetically close to chimpanzees as researchers previously thought.
◦ It shows how much the chimpanzee genome has changed since the divergence of these two lineages.
◦ It shows that the time of divergence of the two lineages is much older than was previously thought.
◦ It shows that more deletions have occurred in humans than in chimps.
◦ It demonstrates the importance of
Alu recombination in shaping genome divergence.
