question 6

Multiple Choice

Use the following information to answer the next few questions.
Poliovirus is a positive-sense RNA virus of the picornavirus group. At its 5' end, the RNA genome has a viral protein (VPg) instead of a 5' cap. This is followed by a nontranslated leader sequence, and then a single long protein coding region (~7,000 nucleotides) , followed by a poly-A tail. Observations were made that used radioactive amino acid analogues. Short period use of the radioactive amino acids result in labeling of only very long proteins, while longer periods of labeling result in several different short polypeptides.
-What conclusion is most consistent with the results of the radioactive labeling experiment?

• A) The host cell cannot translate viral protein with the amino acid analogues.
• B) Host cell ribosomes only translate the viral code into short polypeptides.
• C) The RNA is only translated into a single long polypeptide, which is then cleaved into shorter ones.
• D) The RNA is translated into short polypeptides, which are subsequently assembled into large ones.
• E) The large radioactive polypeptides are coded by the host, whereas the short ones are coded for by the virus.

Definitions:

Expected Capital Gains Yield

The anticipated rate of return from an investment due to an increase in its market price, not including dividends or other income.

Dividend Yield

Defined as either the end-of-period dividend divided by the beginning-of-period price, or the ratio of the current dividend to the current price. Valuation formulas use the former definition.

Strong-Form Efficient

A hypothesis that states all information, both public and private, is completely reflected in stock prices, and no one can consistently achieve higher returns.

Realized Return

The actual gain or loss experienced on an investment over a specified period, taking into account dividends, interest, and capital gains.
