The best way to describe genetic diversity in humans is by describing it as a geographic component of ancestry. That is, human populations gradually change in their allele frequencies in many cases with high geographic precision. This actually makes any differentiation or split into groups very hard.

Is this statement true or false?

In otherwise normal, intact (not leaky), coupled mitochondria supplied with succinate and ADP, if you add the uncoupler CCCP:

a. What happens to electron- transport (works/stops)? Why?

b. What happens to oxygen consumption (works/stops)? Why?

c. What happens to proton pumping (works/stops)? Why?

d. What happens to ATP synthesis (works/stops)? Why?

Biotechnology (Online genetic testing services, GMOs in food debate)

What are the main arguments for and against using genetically modified foods and getting DNA testing online?

Match the vocabulary for Evolution: Species, Populations, Heritable Variation, Adaptations

A) Genetic differences in individuals within a population that can be pass on

B) Groups of the same species in the same geographic area

C) Traits that increase the individuals chance to survive

D) Similar looking organisms that can mate and produce viable offspring

Compare and Contrast infectious diseases, food security and environmental issues in terms of mortality in Mexico and the U.S.. How and why are these countries so different in terms of these topics.

Thanks.

whats the role of small G proteins,Ras? what's the role of small G protein, Rho, Rac and CDC42?

1.) What is the positive control in this experiment? Negative control? Why do you think this?

In otherwise normal, intact (not leaky), coupled mitochondria supplied with succinate and ADP, if you add OLIGOMYCIN:

a. What happens to electron- transport (works/stops)? Why?

b. What happens to oxygen consumption (works/stops)? Why?

c. What happens to proton pumping (works/stops)? Why?

d. What happens to ATP synthesis (works/stops)? Why?

The following is a strand of eukaryotic cDNA

DNA: 5'- catgtctdacagctggccgcca- 3'

a) convert the dna above to its complementary DNA strand (must labe the 5' or 3' ends)

b) dna is converted to mrna is process is called____?

c) convert this dna (5'- catgtctdacagctggccgcca- 3') to its mrna message

d) provide the protein sequence for this dna (5'- catgtctdacagctggccgcca- 3'_

remember this is done in a standard eukaryotic cell.

how to activate a small G protein? how to inactivate a small G protein?

Which of the following can contribute to new traits appearing in bacteria?

1) sexual reproduction

2) all of the other choices are correct

3)mistakes while DNA is copied

4)conjugation

5) two of the other choices are correct

What is the role of decarboxylation in fatty acid synthesis? Name another reaction in a different

metabolic pathway that employs this mechanistic motif.

I know the role is to drive the condensation reaction but I'm stuck on finding another example.

You are following 5 recessive traits in an animal: a, b, c, d, and e. Your student gives you a heterozygous animal, and you testcross this animal. You collect the following 10,000 progeny:

2000    acbe

250      cd

10        c

130      wild type

170      be

220      abe

230      a

2120    ac

10        ad

2100    dbe

180      cad

20        cbe

2150    d

230      cdbe

30        adbe

150      cadbe

A. What is the starting genotype of the heterozygous animal? Indicate which traits are in cis and which in trans.

B. What are the map distances between the genes?

Drug use during pregnancy can include alcohol, tobacco, illicit, and over-the-counter medications. List 4 specific risks that can result from using drugs during pregnancy.

Describe how a poison could affect the electron transport system in cellular respiration. Explain how it happens, the result, and give an example. Be specific but can you also dumb it down.
