Study Questions

1) Describe in detail the process of respiration under anaerobic vs. aerobic condition.

2) How is mRNA modified before it leaves the nucleus of a eukaryotic cell?

3) In what ways are mitosis and meiosis different?

4) A diploid organism has 2n=4 chromosomes. During reproduction each parent contributes half the number of chromosomes to the offspring. Diagram the phases of meiosis to illustrate cell division of this organism. Begin with interphase, where DNA undergoes duplication and crossing over between non-sister chromatids. Your end products should be four haploid daughter cells.

5) How does spermatogenesis differ from oogenesis, and how are the processes similar?

6) What are the events of fertilization?

7) Distinguish between transcription and translation. Where in a eukaryotic cell does each process occur?

8) Draw a diagram to illustrate DNA replication. Your diagram needs to include the direction of DNA replication, enzymes involved, leading and lagging strands, and Okazaki fragments.
