Question 1 1. If a DNA template strand has the base sequence 5' - ATC - 3', what will the corresponding mRNA transcript sequence be?

Question 2 2. Which of the following statements is true of both prokaryotic and eukaryotic gene expression?

Question 3 3. Which of the following are isomers?

Question 4 4. Which of the following mutations is likely to have the largest effect on the sequence of the protein produced?

Question 5 5. Which of the following processes is a main component of aerobic cellular respiration?

Question 6 6. A chart that is used to show how a specific trait, usually a disorder, is passed through a family is known as a:

Question 7 7. Two parents that have the same heritable disorder have an unaffected child. Which of the following is the most likely explanation?

Question 8 8. A cell has duplicated DNA that is uncondensed within the nucleus. Which stage of the cell cycle is this cell likely in?

Question 9 9. Farming practices in which only certain plants with desirable traits are allowed to reproduce have resulted in the evolution of many previously inedible plants into the common vegetables we eat today. This is an example of:

Question 10 10. In a population of birds, the frequency of the dominant and recessive alleles for wing length are equal. A small group of birds are separated from the group and are isolated for 5 generations. In the resulting population, 90% of the birds are homozygous dominant for the wing length trait despite being under the same selective pressures as the original population. The most likely explanation for this phenomenon is:

Question 11 11. The graph depicts the frequency of expression of the range of pigmentation in a population of field mice. Mice on the far left are white and mice on the far right are black, with variations of gray in the middle. Pigmentation is a heritable characteristic. The field mice are preyed upon by birds, which rely on color contrast to find them. Following a volcanic eruption, the primary habitat of the field mice is covered in gray ash. Which of the following graphs of pigmentation expression frequency is likely to result after this selective pressure occurs over a long period of time?

Question 12 12. Which of the following describes the pathway a small particle might take during endocytosis?

Question 13 13. In the figure below, which best describes the process by which sugar molecules move across the cell membrane and into the cell?

Question 14 14. A cell that does NOT have membrane-bound organelles is most likely:

Question 15 15. Red blood cells are placed in a hypotonic sucrose solution. What will most likely occur?
