The Doubly Splice MRNAs Produced by HIV Do Not Contain

question 13

Multiple Choice

The doubly splice mRNAs produced by HIV do not contain the Rev Response Element (RRE) .Which of the following explains why they are transported out of the nucleus without the help of the Rev protein?

• A) They interact with the small subunit of the ribosome, which transport them out of the nuceus
• B) They lack the cis-acting repressive sequences.
• C) The exportin protein binds directly to the mRNAs to transport them.
• D) The inportin protein binds directly to the mRNAs to transport them.
• E) The HIV Rev protein is still required for their export, but it binds to the poly(A) tail instead of the RRE.

Definitions:

Voltage Drop

The amount of voltage required to cause an amount of current to flow through a certain resistance.

Series RL Circuit

An electrical circuit that contains both a resistor (R) and an inductor (L) connected in series, which impacts the phase and amplitude of the circuit's response.

Inductive Reactance

The opposition offered by an inductor to the flow of alternating current in a circuit, quantified in ohms.

Apparent Power

The total power within an electrical circuit, represented in VA (volt-amperes), which combines both real power and reactive power.
