Question

Answers:

For 35: Option E: None of the above.

The exact reason is not known yet for this difference in ratios of A/T and G/C.

For 36: True

For 37: Option B: Reduction in pH decreases affinity of oxygen to hemoglobin

For 38: Option B: Increase in amount of CO2 available decreases affinity of oxygen to hemoglobin

For 39: Option A: Decrease in amount of BPG increases affinity of oxygen to hemoglobin

For 40: Option E: Changes in all kinds of structures of hemoglobin influence the affinity of oxygen. However quaternary structure influences more subtly.

Explanation / Answer

. Which of the following best explains why the ratios of A/T and G/C are 0.77 and 1.08, respectively in bacteriophage pX174 A) the base pairing in bacteriophages is not always A-T and C-G B) studies done with most bacteriophages do not use complete genomic DNA due to the imherent instability of phage DNA C) bacteriophage DNA ofen uses bases other than A, T, C and G D) many viruses often use single stranded DNA E) none of the above 36. term Yo, which An observable parameter used in evaluation of oxygen affinity for heme proteins is the free (unoccupied) sites. ( the fraction of sites occupied by oxygen divided by the number ef True B) False what effect would you expect each ofthe following have gnthumniooLoxygen binding to hemoglobin?
