Sequencing an Entire Genome, Such as That of C

question 38

Multiple Choice

Sequencing an entire genome, such as that of C. elegans, a nematode, is most important because

• A) it allows researchers to use the sequence to build a "better" nematode, which is resistant to disease.
• B) it allows research on a group of organisms we do not usually care much about.
• C) the nematode is a good animal model for trying out cures for viral illness.
• D) a sequence that is found to have a particular function in the nematode is likely to have a closely related function in vertebrates.
• E) a sequence that is found to have no introns in the nematode genome is likely to have acquired the introns from higher organisms.

Definitions:

Stimulus Discrimination

The ability to distinguish between different stimuli, even if they are similar, often used in the context of learning and behavior modification techniques.

Stimulus Generalization

The process by which a conditioned response is triggered by stimuli that are similar but not identical to the original conditioned stimulus.

Systematic Desensitization

A behavioral therapy technique used to reduce phobic responses and anxiety by gradually exposing the individual to the feared object or situation in a controlled way.

Counterconditioning

A behavior therapy technique that involves pairing a positive stimulus with a fear-evoking stimulus to reduce the fearful response.
