of six atoms, and^ , a fused^
double ring of nine atoms of carbon and nitrogen.^

6. Adenine always pairs with^ , and^
   cytosine always pairs with^.^
   7. The nitrogen base pairs of the two chains of
   the DNA molecule are held together by^

8.

(^) bonds. (^)
Cellular division in the nucleus producing- two (^)
(^) identical- nuclei is known as. (^)
9. is a reduction division of (^)
(^) the nuclear material so that each gamete contains (^)
only half as much genetic material as the parent.^

1. Exchange of genetic material between homologous
   chromosomes occurring in prophase I of meiosis is^
   called.

11. The number of cells produced after a mitotic
    division is , whereas the number of cells
    produced after meiosis is^

12. Meiosis occurs only in the
    of the human body.

EXERCISE:

Cellular Reproduction

1. Your instructor will show you a videotape or
   a CD-ROM on cell division. A suggestion is
   the Center for Humanities videotape “Mito-sis
   and Meiosis: How Cells Divide.”^


2. Set up your compound light microscope and
   observe the stages of mitosis by looking at
   slides of the whitefish blastula (animal) and
   an onion root tip (plant). Draw and la-bel cells
   showing the following stages: in-terphase,
   prophase, metaphase, anaphase, and
   telophase.
   3. Examine a prepared slide of human sperm.
   Draw and label the parts of a sperm cell.^
   4. Examine a prepared slide of the chromo-
   somes of a fruit fly, Drosophila, from a smear
   of the fly’s salivary gland.^
   5. Construct a portion of a DNA molecule from
   a kit supplied by your instructor.^
   6. Utilizing a chromosome simulation biokit,
   construct chromosomes with colored beads
   representing genes and replicate the stages of
   the mitotic cell cycle.
