Question 1

Several of the different globin genes are expressed in humans, but at different times in development. Which of the listed mechanisms could allow for this?

Accepted Answer

A)   exon shuffling
B)   pseudogene activation
C)   differential translation of mRNAs
D)   differential gene regulation over time

Question 2

Bioinformatics can be used to scan for short sequences that specify known mRNAs, called ________.

Accepted Answer

A)   expressed sequence tags
B)   multigene families
C)   proteomes
D)   short tandem repeats

Question 3

Which of the following processes correctly describes gene annotation in bioinformatics?

Accepted Answer

A)   finding transcriptional start and stop sites, RNA splice sites, and ESTs in DNA sequences
B)   assigning names to newly discovered genes
C)   describing the functions of noncoding regions of the genome
D)   matching the corresponding phenotypes of different species

Question 4

Studies in knockout mice have demonstrated an important role of the FOXP2 transcription factor in the development of vocalizations. Recent sequence comparisons of the FOXP2 gene in Neanderthals and modern humans show that while the DNA sequence may be different, the protein sequence it codes for is identical. Which of the following conclusions might logically be inferred from this information?

Accepted Answer

A)   There was a problem with the experiment because different DNA sequences cannot result in the same protein sequence.
B)   The differences in DNA sequence support the hypothesis that Neanderthals were primitive beings that could only grunt.
C)   Human and Neanderthal vocalizations may have been more similar than previously thought.
D)   The experiments in mice demonstrating the function of the FOXP2 gene are not relevant to humans and Neanderthals because they are not primates.
