Which of the following statements about antidiuretic hormone (ADH) in prairie and montane voles is not correct?
A. The receptor for ADH is found in the kidney where it contributes to water conservation and in the brain where it influences behavior. B. Both the prairie vole and the montane vole produce ADH. C. The ADH receptor differs between the prairie vole and the montane vole. D. The ADH gene with is distinct regulatory region was taken from the prairie vole and inserted into the montane vole. The prairie vole then became promiscuous. E. The regulatory sequence and ADH coding region of the prairie vole was inserted into the montane vole which then became more likely to pair bond.

Which structure is common to both prokaryotic and eukaryotic cells?
A) Nucleus B) Ribosomes C) Chloroplasts D) Mitochondria
In retroviruses, there is a stop codon at the end of the reading frame for the first gene
However, in about 5% of the proteins, the stop codon is bypassed, resulting in translation of the second gene and synthesis of a fused protein representing both genes 1 and 2. How is the stop codon bypassed if the reading frames of the first and second genes are different? What will be an ideal response?
