BIO 103  - TEST 4 STUDY GUIDE

Fall 2007

 Chapter 9:

 You should know what binary fission is.

 You should know what occurs in the three basic components of the cell cycle:

Interphase, Mitosis, and Cytokinesis. Know which of these takes the longest period of time to complete.

 You should know what happens in each specific component of the cell cycle including:

G1, S, and G2 phases of interphase; prophase, metaphase, anaphase, and telophase of mitosis. Be able to visually recognize all stages of mitosis and all specific structures that we discussed. These include spindle fibers, astral rays, chromosomes, cell plate, and cleavage furrow.

 Know the following terms: Chromosomes, sister chromatids, chromatin material, spindle fibers, astral rays, cell plate, cleavage furrow, haploid (1N), diploid (2N), cell cycle.

 

Chapter 10:

 You should understand the basic differences between mitosis and meiosis.

 You should know what occurs in each phase of the Meiosis process ( ex. Prophase I, Metaphase II, etc.)

 You should know the following terms: synapsis, crossing-over, chiasmata, gamete, zygote.

 

Chapter 11:

You should be familiar with Mendel’s First and Second Laws.

You should know the following terms: genotype, phenotype, heterozygous, homozygous
(dominant and recessive), punnett square, testcross, allele, codominance, and incomplete dominance.
You should be able to recognize all genotypic symbols ( ex. HH, Hh, hh ).

You should be able to work through a variety of monohybrid crosses and interpret the results as far as genotypic and phenotypic probabilities are concerned. You should also be able to complete and interpret a dihybrid cross.
