2. A cell has a diploid number of chromosomes = 34 (2n = 34). (a) How many chromosomes will the daughter cells have after mitosis? (b) How many chromosomes will the daughter cells have after after Meiosis I? (c) How many chromosomes will the daughter cells have after after Meiosis II?

3. Describe each of these activities and identify in what stage of meiosis they occur: (a) crossing over (b) independent assortment of homologous chromosomes

Cystic fibrosis is caused by a mutation in a single gene. Homozygotes for this mutant recessive allele (ff) have cystic fibrosis. Within a population, 2% of people have cystic fibrosis. Assuming Hardy-Weinberg equilibrium, the frequency of heterozygotes in the population is 0.24.

If inbreeding was common in this population, what would happen to the percentage of people who have cystic fibrosis over time?

9. Which of the following statements about the building blocks of polymers is true? a. When looking at the complete structure of a nucleotide you can always tell whether it is considered a ribo-nucleotide or a deoxyribo-nucleotide. b. When looking at a glucose monomer (in linear form), you can always tell which polymer of glucose (a starch or cellulose) it will be incorporated into. c. When looking at a single amino acid, you can always tell whether it will be the last amino acid in a polypeptide chain. d. When looking at a nitrogenous base, you can always tell if it will be incorporated into a doublestranded nucleic acid or a single-stranded nucleic acid. e. There is more than one correct answer

A. Describe three important differences in the transcription of mRNA's between bacterial and eukaryotic cells.

B. In the synthesis of cDNA libraries for eukaryotic genes, reverse transcriptase can be used with a primer containing poly(T). Why is this NOT useful for prokaryotic systems?

6. Which of the following would you expect to result from a block of electron transfer at complex II. Check all correct answers and explain.

a. Reduction in oxidative phosphorylation

b. No change in the proton gradient across the inner mitochondrial membrane

c. FADH2 accumulation

d. Damage to the cells due to reactive oxygen species accumulation

2. Compare and contrast sporogenesis and gametogenesis in anther and ovary (of angiosperms). You must use, but are not limited to, the following terms: anther, eggs, embryo sac, generative cell, microsporocytes, megasporocyte, microspores, pollen sacs, pollen grain, 2 nucleate, 4 nucleate, 8 nucleate, polar nuclei, sperm, synergids, tetrads, tube cell,

Describe if the following homozygous mutant plants will undergo the triple response in the presence and absence of ethylene. Briefly explain your answer.

A. A recessive mutation (loss-of-function) in the EIN3 gene. This recessive mutation results in EIN3 being unable to activate the expression of ethylene inducible genes.

B. A recessive mutation (loss-of-function) in one ethylene receptor gene (ETR1). This recessive mutation resulted in an ETR1 protein that is unable to activate CTR1.

C. A dominant mutation (gain-of-function) in one ethylene receptor gene (ETR1). This dominant mutation results in an ETR1 protein that is unable to bind ethylene.

D. A dominant mutation (gain-of-function) in EIN2. This dominant mutation results in an EIN2 protein that cannot be phosphorylated by CTR1.

5. Describe and illustrate all of the following life cycles: mosses, ferns, gymnosperms, and angiosperms.

In same cases of ADD (attention deficit disorder) the impulsive, erratic behavior can be normalized with drugs that stimulate the central nervous system. Explain this finding in terms of neurotransmitter activity in the brain.

Two out of every three known animal species are arthropods. Describe the general body plan of an arthropod, give an example of an organism belonging to each of the three major groups (Cheliceriformes, Myriapoda, and Pancrustacea); and explain why the arthropods have been so successful.
