Some RNA viruses direct the synthesis of double-stranded DNA at some point in their life cycle. true or false?
To be of value, DNA sequences targeted for analysis for DNA profiling need to be located in coding regions of the genome. true or false
Homework Answers
True some RNA virus direct the synthesis of double stranded DNA. This is VI group of Baltimore classification of viruses.
False for DNA profiling the region of short tandem repeats (STR) of non coding regions are required.

2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...

Which of the following is TRUE of incomplete penetrance? Select one: a. Epistatic interactions can result in incomplete penetrance in some cases. b. Environmental factors do not influence penetrance. c. Incomplete penetrance implies that some individuals will experience less severe forms of disease, such as cancer or Alzheimer's. d. Incomplete penetrance is never observed with Huntington's disease e. Incomplete penetrance refers to cases in which individuals developing a particular disease (e.g., cancer or Alzheimer's) lack the typical genotype for this...
