You wish to develop an antitoxin therapeutic. Your plan is to create a molecule which will inactivate the ability of the toxin to penetrate the cell membrane, thus preventing the toxic effects. You decide to base the therapeutic on an aptamer design. a. What is an aptamer (5 pts) b. How would an aptamer function to protect the cell from the toxin

16. In peas, tall plants (T) are dominant to short (t) and purple (P) is dominant to white flower color (p). What are the phenotypes of cross between ttPp and TtPP?

when you need the components of the question above to grow a certain bacteria, and the bacteria grow in closed tubed in a closed dark, non-shaking incubator that is set at 54C, which definition correctly applies to these bacteria:

a. photo-heterotroph

b. halophile autotroph

c. heterotrophic thermophile

d. aerobic psychrophile

e. alkaliphilic acidophile

1. Heterotroph – Yes, the bacteria need glucose but the overall answer is NO because of the fact that there is no light
2. Autotroph: NO, because it needs glucose, so the overall answer is NO

The answer say like this, but I can't understand about glucose. It is because of the non-shaking incubator?

1) Suppose that a certain population of 100 individuals possesses two alleles (A and B) at a certain locus, and initially consists of the following numbers of genotypes: AA = 9, AB = 42, BB= 49.

a) Calculate the initial frequencies of alleles A and B.

b) Now suppose that 16 individuals with genotype BB do not survive to reproduce. Calculate the new allele frequencies among the remaining individuals that do reproduce. Assuming that these remaining individuals mate randomly, calculate the new genotype frequencies in the next generation. Use the following headings to organize your calculations.

  New Allele Frequencies

New Genotype Frequencies

An avid gardener plants a kiwi vine in the backyard. After many years, in spite of luxuriant growth and many pollinating bees in the backyard, the tree does not bear fruit. All the blooms display lovely white flowers and a large carpel with long sticky stigmas in the center. What is a possible explanation for the problem?
