Haploid yeast cells that preferentially repair double-strand breaks by homologous recombination (rather than by non-homologous end joining) are especially sensitive to agents that cause double-strand breaks in DNA. If the breaks occur in the G1 phase of the cell cycle, most cells will die; however, if the breaks occur in the G2 phase, a much higher fraction of cells survive. Why do you suppose this is?

7-3 Developing a:B T cells are better at successfully coding for a ß chain than developing B-2 cells are at successfully coding for a Heavy chain because they (a:ß T cells ) have a. more D genes for the ß chain b. two sets of ß chain D-J gene segments per chromosome c. more efficient RAG proteins d. CD4CD8 double positive cells always are a:ß T cells

Since AMP can also be hydrolyzed to release energy, why do cells bother to use ATP (which requires the cell to have more phosphate) to power cellular reactions? Question 1 options: a. ATP fits better into enzymes. b. ATP hydrolysis releases more energy than AMP hydrolysis. c. ATP stores for a longer time than AMP. d. Cells have more than enough phosphate, and it serves few roles anyway.

Why are cells able to produce much more ATP per sugar molecule when oxygen rather than an organic molecule is used as the terminal receptor?

D. On the surface of red blood cells there is a passive antiporter than moves bicarbonate and chloride ions in oppòsite directions. Bicarbonate is produced from carbon dioxide and water by the activity of an enzyme called carbonic anhydrase. Chloride as well as several other inorganíc ions have been shown to reduce oxygen affinity by hemoglobin when these anions are bound to the central cavity Why is it important that this transporter is an antiporter? In what circumstances will bicarbonate...

5) Iodine is a better leaving group than bromine. But iodine is
a better nucleophile than bromine. Why is that?
Introduction Alkyl halides can be prepared from alcohols by reactions with hydrogen halides (HCI, HBr, or HI) via nucleophilic substitution. In this type of reaction, the nucleophile displaces a leaving group from a carbon atom of an organic substrate (here the alcohol once protonated). Both electrons of the new bond to the carbon are provided by the nucleophile while the...

1. Why is iPS cell therapy using third-party donor cells more feasible than using cells donated from the patient being treated? O Treatment with iPS cells is much more cost prohibitive when iPS cells are donated by the patient being treated. O Donor iPS cells from the patient cannot be used because they contain the disease being treated. O Third-party donor cells are less likely to contain dangerous mutations that can lead to tumor formation. O Third-party donors are screened...
