What are some genetic differences between prokaryotic and eukaryotic cells?

Outline the process by which prokaryotic cells reproduce.

Name three essential structural elements of a functional eukaryotic chromosome and describe their functions.

List the stages of interphase and the major events that take place in each stage.

A certain species has three pairs of chromosomes: an acrocentric pair, a metacentric pair, and a submetacentric pair. Draw a cell of this species as it would appear in metaphase of mitosis.

How are the events that take place in spermatogenesis and oogenesis similar? How are they different?

A cell in prophase II of meiosis contains 12 chromosomes. How many chromosomes would be present in a cell from the same organism if it were in prophase of mitosis? Prophase I of meiosis?

Normal somatic cells of horses have 64 chromosomes \((2 n=64) .\) How many chromosomes and DNA molecules will be present in the following types of horse cells? $$\begin{array}{ccc} \text { Cell type } & \text { Number of chromosomes } & \text { Number of DNA molecules } \\ \text { a. Spermatogonium } & \text {_____} & \text {_____} \\\ \text { b. First polar body } & \text {_____} & \text {_____} \\ \text { c. Primary oocyte } & \text {_____} & \text {_____} \\ \text { d. Secondary spermatocyte } & \text {_____} & \text {_____} \\ \end{array}$$

Indicate whether each of the following cells is haploid or diploid. $$\begin{array}{cc} \text { Cell type } & \text { Haploid or diploid? } \\ \text { Microspore } & \text {_____} \\ \text { Primary spermatocyte } & \text {_____} \\ \text { Microsporocyte } & \text {_____} \\ \text { First polar body } & \text {_____} \\ \text { Oogonium } & \text {_____} \\ \text { Spermatid } & \text {_____} \\ \text { Megaspore } & \text {_____} \\ \text { Ovum } & \text {_____} \\ \text { Secondary oocyte } & \text {_____} \\ \text { Spermatogonium } & \text {_____} \\ \end{array}$$
