Hagrid, the Hogwarts gamekeeper, is fascinated with dragons. A true-breeding Common Welsh Green Dragon with green scales (b+), brown eyes (p+) and a smooth tail (s) was crossed to a true-breeding Hebridean Black Dragon with black scales (b), purple eyes (p) and a spiked tail (s+). All of the F1 dragons had green scales, brown eyes and a smooth tail. When the green scaled, brown eyed and smooth tailed F1 females were crossed to true-breeding black scaled (b), purple eyed (p), spiked tail (s) males the following results were obtained. Please answer the following questions.

Show the configuration of these three genes including the distance between any linked genes.

1. In the boxes in the flow chart below, follow the flow of carbon atoms in the complete oxidation of glucose by indicating the beginning and ending molecules in each of the steps of cellular respiration starting with 1 molecule of glucose. Be sure to include the number of molecules of each type of molecule made from 1 molecule of glucose at each step. (Do not include other molecules made like NADH and ATP).

a) Describe one measure of evolutionary fitness.

(c) Based on the data, identify the population that is likely to have the highest frequency of heterozygotes. Assuming random mating, calculate the frequency of animals in population 1 that carry both alleles 1 and 3.

d) A sudden event drastically changes the habitat of each population such that most of the normal vegetation and insects are replaced by other vegetation and insects. One of the scientists claims that population 2 will be the most severely affected. Predict the most likely effect of the event on population 2. Provide reasoning to justify your prediction.

Discuss the infection of a bacterium by a virus. Include the steps in the correct order from attachment to lysis. How does this differ from the virus replication cycle in animals? Explain the difference between the lytic cycle, lysogeny, and slow release. Also include the bacterial defense mechanism bacteria have developed to prevent infection by a virus. How is this bacterial defense now being used to modify genetic codes in humans, include CRISPR in your discussion. Explain the growth curve of a virus and what phase is the coronal virus in the present pandemic?

Explain the importance of evidence-based practice with wrist orthotic provision.

In class we discussed the calculation of the P/O ratio assuming a c-ring comprised of 9 subunits. How would the P/O ratio change (for both NADH and succinate/FADH2) if a particular mitochondrion had FOF1-ATP-synthase molecules whose c-ring were composed of 12 subunits rather than 9? The best answer will explain your reasoning and show the calculation for each. (5 points)

Describe what is similar and what is different about metabolic pathways used by a lithoheterotroph versus a lithoautotroph using ALL of the following terms: electron donor, electron acceptor, reduced, oxidized, organic carbon, and inorganic carbon.

1a. Many uridine molecules are inserted into some mitochondrial mRNAs in trypanosomes.  The uridine residues come from the poly(U) tail of a donor strand!  Nucleoside triphosphates do not participate in this reaction.  Propose a reaction mechanism that accounts for these findings.  (HINT:  relate this RNA editing to RNA splicing.)

b. Analysis of  p53 gene mutations in human tumors shows that a large proportion of these mutations involve GC→AT transitions originating at sites of DNA methylation.  Propose a model to explain preferential mutagenesis of this type at these sites.

Phenol red, a pH indicator, is used in the experiment to determine respiration activity by showing CO2 production.

Questions;

1. How does phenol red work as a pH indicator?

2. Why does this show respiration activity?
