B. Short Answer/Short Essay Questions

Instructions: Answer each of the questions given below in your own words. Write in complete sentences where appropriate. A complete answer usually requires one to two sentences per mark, so a three-mark question would be answered in three to six sentences. This section is worth a total of 40 marks.
1. Draw two cells, one showing the arrangement of chromosomes at metaphase of mitosis, and the other showing the chromosomes at metaphase I of meiosis. Describe how the arrangements differ and how this relates to variation in the daughter cells.
2. Compare and contrast DNA synthesis in prokaryotes and eukaryotes.
3. What are restriction enzymes? How are they used in cloning?
4. Gene regulation in eukaryotes occurs on several levels. Which level of gene regulation is most important? Describe one example of the the most important level of gene regulation.
5. The lac operon in E. coli is subject to both positive and negative regulation. Describe and explain both in detail.
6. What are the three main types of RNA, and what are their roles?
7. What is the proofreading mechanism of DNA, and which enzymes are involved?
8. Using the following DNA template strand sequence, answer the questions below: 3’–TACCGGCACGATTAG–5’ a. What is the mRNA sequence? b. List the anticodons for each tRNA involved in translation of the sequence. c. What is the final sequence of amino acids in the peptide produced?
