What is the purpose of synthesizing a negative strand RNA in positive stranded ssRNA viruses?
A) enable rolling circle amplification of the genome, which requires both strands of RNA B) enable transcription of genes occurring on both the negative and positive strands of the genome, such as overlapping genes C) proofreading of the genome to minimize mutations generated by the polymerase being passed onto virion progeny D) to serve as the complementary template sequence in genome amplification of the positive strand
The loop of Henle in the nephrons of desert-dwelling kangaroo rats is much longer than the loop of Henle in humans. What is the advantage of this increased length for the kangaroo rat?
A. A longer loop of Henle can generate a larger concentration gradient, which allows for the production of a more concentrated urine. B. A longer loop of Henle can generate a smaller concentration gradient, which allows for the production of a more concentrated urine. C. A longer loop of Henle can generate a larger concentration gradient, which allows for the production of a less concentrated urine. D. A longer loop of Henle can generate a smaller concentration gradient, which allows for the production of a less concentrated urine. E. None of the answer options is correct.
