Describe the 5 events that convert an mRNA into a cDNA.

Peregrine falcons are one of the several species of raptors whose populations declined       dramatically in the mid-60's after exposure to pesticides that caused them to lay very thin-shelled eggs.  In fact, the population in eastern North America disappeared entirely, but birds have been reintroduced.  Even though use of DDT has been banned in the USA, it is still used elsewhere, and is manufactured in the USA, and so species such as peregrines are still exposed to some extent to these toxins.  At a locus coding for an enzyme involved in laying down calcium in the eggshell, birds of genotype AA lay perfect eggs, while those that are Aa suffer 10% egg breakage (s_Aa = 0.10), and those that are aa suffer 70% egg breakage (s_aa = 0.70).  The original populations starts with 450 individuals of genotype AA, 380 of genotype Aa, and 170 individuals of aa.  

(a)  What is the starting allele frequency for the (A) allele (in other words, what is p₀)?   What would the allele frequency for the (A) allele be in the adults after one generation (what is p₁)?

(b)   If the p₁ generation of adults reproduced by random mating, how many chicks in the population would you expect to find with the aa genotype (the most fragile) if you counted a total of 100 baby falcons?

Part 2. Answer both:

1. How would you determine whether the morphological diversity of animals has increased, decreased, or stayed the same since the Cambrian? Explain what kind of data you would collect, how you would analyze it, and what sorts of biases you might need to correct for.
2. Choose three species of wild organisms (not domesticated species or humans) and predict how their populations and geographic ranges will change in the future, assuming that global climate change continues at its current rate.

Describe how energy from sunlight is converted into chemical energy in the form of ATP. Be thorough.

1. The prevalence of most psychological disorders has increased since the 1980s. In addition, no fictional or nonfictional description of individuals showing dissociative amnesia following a trauma exists prior to 1800. How would you explain this phenomenon?

2. Find an example (via a search engine) of a past instance in which a person committed a horrible

crime, was apprehended, and later claimed to have dissociative identity disorder during the trial. What

was the outcome? Was the person revealed to be faking? If so, how was this determined?

A. State the number of ATP molecules that are formed from the complete breakdown of one glucose molecule.

You want to use PCR to amplify a 1Kb exon of the human autosomal gene phenylalanine hydroxylase (PH) from the genome of a person suffering from the disease phenylketonuria, which is due to this enzyme not functioning.

a) You start with 1 nanogram of genomic DNA in your sample tube. Assuming a human haploid genome is 3 x 109 bp, and each bp has a mass of 660 g/mole, how many moles of haploid genomes are present at the start of your PCR experiment?

b) The PH gene is present in a single copy in the haploid genome. How many template molecules of the PH gene are present at the start of your PCR experiment? (Give your answer in molecules, not moles of molecules.)

c) You set your PCR machine to run for 25 cycles to amplify your 1 kb fragment. Assume every cycle exactly doubles your desired target DNA. At the end of your 25 cycles, how much amplified DNA have you created, in terms of number of molecules AND mass of DNA?

For each precursor molecule, identify the corresponding class of hormone (catecholamine, eicosanoid, peptide, or steroid) and give an example.

(b) cholesterol

(c) prohormone

(d) tyrosine
