How Does the Gp32 Protein Facilitate Both Stabilization of Single-Stranded

question 22

Multiple Choice

How does the gp32 protein facilitate both stabilization of single-stranded DNA as well as its renaturation to double-stranded DNA?

• A)gp32 is an enzyme and thus its reaction of separating DNA strands is freely reversible
• B)gp32 binds only to regions of high A and T content so hydrogen bonding is reversible
• C)gp32 displays cooperativity in binding to single stranded DNA
• D)the gp32 C-terminal domain acts as a switch between weak and strong single stranded DNA binding
• E)none of the above

Definitions:

Habituation

The process by which an organism decreases or ceases its responses to a repetitive stimulus over time.

Behavioral Contrast

A phenomenon where the rate of response to a stimulus changes significantly when the conditions of reinforcement for another stimulus are altered.

Higher-order Conditioning

A form of learning in which a stimulus is first made meaningful or consequential for an organism through an initial step of learning, and then that stimulus is used as a basis for learning about some new stimulus.

Disinhibition

The reduction of inhibition, leading to an increase in spontaneous and unrestrained behavior, often as an effect of alcohol or neural damage.
