1)  What are the four inputs to the Calvin cycle needed to produce glucose? (Hint: there are two carbon containing molecules, and two energy-related molecules) What role do these molecules have within the cycle? 2) Explain how glucose is produced without running out of RuBP. Include the number...

The pea (Pisum sativum) has 7 distinct chromosomes. Mendel examined 7 genes, but not all were on different chromosomes, as shown in the table below. If he had done dihybrid crosses with certain pairs of traits, he might never have figured out the laws of...

16. You have read in the Human Perspective that (1) mutations in the can ace- rm? pro- PRNP gene can make a polypeptide more likely to fold into the PrPSe conformation, thus causing CJD and (2) exposure to the PrPSc prion can lead to an...

complete solutions. 1)A Quarter Horse breeder has a stallion that they suspect may have had a parent that was dual registered in the paint herdbook. Although rare, it is possible for a solid coloured stallion to carry the lethal white overo allele. In order to test...
