Do you guys think, this is a vague question? Nucleotides are linked by: a. H-bonds b. Phosphodiester bonds c. Covalent bonds d. VanderWalls e. Gycosidic bonds The key says the answer is A, but could B, be the answer to since nuclotides adjacent to each other are linked by phosphodiester bonds. Also, will there be vague question with two answer on the test and we have to pick the most wrong one!? (That would be crazy)! Here is another vague one from Topscore: Which controls the breathing function a. Pons b. Medulla c. Hypothalmus d. A and C e. A and B The answer is E. I guess E is the most correct although could B, be the right answer too or not!?
