20) When a mutation leads to a substitution of a different amino acid within a protein, this is a _________________ mutation. A. nonsense B. missense C. silent D. deletion

21) Which of the following is true about evolution by natural selection? A. The goal of evolution is to arrive at humans. B. When evolution is complete, a perfect species exists C.

19. Pick the correct answer. When a gene of interest has been inserted into a plasmid vector, the result is called _____ DNA. homologous analogous recombinant heterologous restriction fragment Restriction sites are often DNA _____, which means that both DNA strands constituting the restriction site have the same DNA sequence but in _____ orientation. donors; parallel palindromes; parallel palindromes; antiparallel vectors; antiparallel hybrids; parallel The restriction enzyme XYZ-1 cuts DNA in one strand of a double-stranded DNA molecule at the...

Consider two genes with different expected mutation rates due to size. Gene 1 has a mutation rate of 1 x 10-6 in the population, while gene 2 has a mutation rate of 3 x 10-6 in the population. Assume that the probability for an individual to have two mutations in one gene is 0. Also, the number of bases, n, in a gene is large. State the probability for gene 1 and for gene 2 that there is exactly one...

A patient has a genetic mutation in the gene for glutaminase that significantly reduces the efficiency of this enzyme, leading to a decrease in glutamatergic signaling. Which of the following could potentially compensate for this? a. A downregulation of aspartate aminotransferase b. A downregulation of VGLUT c. An upregulation of neuronal glutamate transporters d. An upregulation of VIAAT

Presume a couple found out their embryo has a gene mutation that has a high success rate of causing cancer later on in the baby’s life. Would you advocate the use of gene therapy in the embryo to correct the problem before the child was ever born? What if the embryo did not appear likely to develop a genetic disease, but the parents decided that they would really prefer that their child have blue eyes as opposed to brown? Would...
