Explain how a single gene effects two or more independent pathways using the example of an white eye phenotype for a fruit fly. Propose three hypothesis with details and explanation.

Explain pharmacokinetic interactionsunder ADME. Give an example to each one and mention the outcome of these interactions. Please write me long :) thanks you.

1. A measure of yeast cells preparing for mating is:

2. The alpha mating factor pathway signals through a:

3. A malignant tumor is more dangerous than a benign tumor because ______________________.

A butterfly shaped rash across the nose and cheeks is a common characteristic of?

Lupus, rheumatoid arthritis, myasthenia gravis, hashimotos thyroiditis

"Thr-91 of Complex I is conserved through evolution. It is crucial for the functioning of Complex I in the Electron Transport Chain. I make two forms of mutant yeast: one in which Thr-91 is mutated to an alanine (Thr91Ala) and another in which Thr-91 is mutated to a tryptophan (Thr91Trp)."

Base on the data given, CREATE YOUR OWN QUESTION (best if can relates to electron transport chain of metabolism pathway). Then, find an ANSWER to your own question.

JJ KK and jj kk individuals (parents) were crossed to each other, and the F1 were testcrossed to the jj kk parent strain. The resulting offspring were: 999 Jj Kk : 999 jj kk : 1 Jj kk : 1 jj Kk. How would the testcross progeny ratios differ if the parents were JJ kk and jj KK instead?

Multiple Choice

• >9 Jj Kk : >1 jj kk : <3 Jj kk : <3 jj Kk

• 1 Jj Kk : 1 jj kk : 999 Jj kk : 999 jj Kk

• They would not change.

• 1 Jj Kk : 1 jj kk : 1 Jj kk : 1 jj Kk

• 9 Jj Kk : 3 jj kk : 3 Jj kk : 1 jj Kk

• <9 Jj Kk : <1 jj kk : >3 Jj kk : >3 jj Kk

If DNA primase incorporated a mismatched nucleotide, how would that affect the organism? Justify your answer.

Consider the following substances: alcohol, penicillin and rifamycin. Which of these substances would likely have the broadest spectrum of activity against microbes? Why? Identify one downside associated with this substance and its broad-spectrum activity.

You and 99 friends are on a three hour boat tour when the weather started getting rough and you were stranded on a desert island. Three of you friends are carriers of the gene for albinism, but no one on the trip is albino. What percentage of the island’s population in the next generation do you expect to be albino? Carriers of this gene?  

Assume that the albinism gene above also allowed individuals who are carriers to avoid a deadly illness caused by consuming the seaweed that grows on the island – one of the few food sources available. Do you predict that will impact the frequency of that allele in the gene pool?Assume that the albinism gene above also allowed individuals who are carriers to avoid a deadly illness caused by consuming the seaweed that grows on the island – one of the few food sources available.

How are vaccines made? - Why do they take so long to make? - Why can't you just walk into Walgreens and buy a vaccine for Covid-19 yet?

Albinism is a rare autosomal recessive trait in which there is a complete absence of melanin pigment in the skin, eyes, and hair. A normally pigmented woman whose parents are normal has a brother who is albino. She marries a normally pigmented man whose grandfather was albino. What is the probability their first child will be albino?

I would like to see the problem worked out. Dont understand why it is 1/12. Thank you in advance

This topic's discussion focuses on the basic processes of how cells are able to do what they do--the central dogma of life. In order for cells to function effectively, they need to make proteins, which, as we learned way back in Topic 2 (Ch. 4) are responsible for doing all of the work inside of (and for) the cell (enzymes) and provide the necessary structure for cells to function (cytoskeleton, some signaling molecules, binding proteins, receptors, transporters, etc.). Each cell has all of the information the organism needs to make these proteins (in the form of genes on chromosomes--the DNA), although it only makes the proteins that it needs when it needs them. The processes of reading the DNA to make the RNA and reading the RNA to make the proteins are together known as the central dogma (and sometimes DNA replication is included since it is also required for living organisms to make new cells). Your discussion postings this week should focus on some aspect of the central dogma and provide more detail for your fellow classmates. For example, one of the parts and how it is controlled, where it occurs, what can go wrong, or how they're connected. Along with the responses, this discussion should give you a much better understanding of how life actually works! Do not use other solutions. I need originality responses as well as IN TEXT CITATIONS AND A WORKS CITED REFERENCE. Please use 2 outside references.Thank you
