Document Summary

If there are 2 alleles at a locus, p and q represent their frequencies: p + q = 1: the hardy-weinberg model states that allele and genotype frequencies remain constant, genotype frequencies: p2, hardy-weinberg equilibrium. Chapter 1: introduction: overview: the study of life, levels of organization, emergent properties: the whole is greater than the sum of its parts, ecosystems communities: deer and plants populations: herd of deer . Organism: one deer organs and organ systems tissues cells organelles. All of the descendants: parsimony is used to infer a phylogeny, maximum parsimony: the simplest (evolutionary change) is the most likely; given a set of alternatives. 5" 3" directions (antiparallel) arrangement: the nitrogenous bases in dna pair and h-bond: adenine (a) with thymine (t), guanine (g) with cytosine (c); complementary base pairing (also in trna) Chapter 4: cells and organelles: cells: the fundamental units of life.

Part A:

In prokaryotes and eukaryotes cell reproduction is similar in that it requires some kind of signal to proceed, DNA replication, careful separation of the DNA into two equal portions, and division of the cytoplasm. How is cell reproduction different in prokaryotes and eukaryotes?

Select one:

a. In a eukaryotic organism, the signals for cell division are usually not related to the environment but to the function of the entire organism.

b. Eukaryotic cells constantly divide whenever environmental conditions are adequate and the cells are large enough.

c. The linear chromosomes in prokaryotes are constantly being updated.

d. Prokaryotic cell division requires cytokinesis before mitosis because of their small size.

e. The sexual phase of most prokaryotes (bacteria) is essential to the rapid cell division required for infection.

What does the name Cyclin Dependent Kinase stand for?

Select one:

a. A protein important to the cell cycle that is dependent on DNA synthesis.

b. An enzyme that cuts DNA so that chromosomes can segregate.

c. An enzyme that phosphorylates other proteins using ATP only when the protein Cyclin is bound to the enzyme.

INTERPHASE

How many chromosomes are present in the somatic cell?

What do they look like?

What are they âdoingâ in G1 of this phase?

What is happening in the S phase?

What follows G2 phase in a gamete cell?

MITOSIS

Number of chromosomes in the parent cell.

Number of chromatids in the parent cell.

Number of chromosomes in the daughter cell.

Number of chromatids in the daughter cell.

How many daughter cells are produced?

Meiosis 1:

Number of chromosomes in the parent cell.

Number of chromatids in the parent cell.

Number of chromosomes in each Meiosis I daughter cell.

Number of chromatids in each Meiosis I daughter cell.

Are the daughter cells haploid or diploid at the end of Meiosis 1?

Meiosis II:

Number of chromosomes in the âparentâ cell (which is a daughter cell from Meiosis I).

Number of chromatids in the âparentâ cell.

Number of chromosomes in each Meiosis II daughter cell.

Number of chromatids in each Meiosis II daughter cell.
