With the initial appearance of the feature we call “Now Solve This,” a short introduction is in order. The feature occurs several times in this and all ensuing chapters, each time providing a problem related to the discussion just presented. A “Hint” is then offered that may help you solve the problem. Here is the first problem: (a) If an organism has a diploid number of 16, how many chromatids are visible at the end of mitotic prophase? (b) How many chromosomes are moving to each pole during anaphase of mitosis?
