8. Question 1
The assembly of a messenger RNA strand that normally begins with UAC has been changed so that the newly assembled messenger RNA strand begins with UAG. Which of the following will most likely occur?
A The protein will be missing the first amino acid.
B The amino acids that make up the protein will all be different.
C The mRNA will become attached to a ribosome.
D The production of the protein will be stopped.
Answer: a; solute dissolve more quickly at higher temperatures.

9. Question 2
The diagram above shows chromosomes in a cell undergoing cell division. If one of the chromosomes breaks during this process,
which of the following will most likely happen?

10. Question 3
The diagram shows three generations of cells produced by a single cell through mitosis. In the process, a single mutation occurred at the point indicated. The mutation caused changes within a dominant allele. How many of the 15 cells contain the mutation?
Answer: a; solute dissolve more quickly at higher temperatures.
