Monastrol is a drug that affects mitosis by inhibiting Eg5, a motor protein needed for centrosome separation and involved in the formation and maintenance of the mitotic spindle apparatus.
Imagine that a cell with four chromosomes was treated with
Monastrol in late G2. In the space provided, draw what you would
expect the cell to look like in prometaphase:

32. Study the signaling pathway illustrated below, which involves two different receptors. Assume that a protein is active only when it is activated, but not inhibited, by its upstream signaling molecules. Activation and inhibition are indicated by normal and blunt arrows, respectively. Assume that the transcription regulator can be activated by either the binding protein or the kinase that are immediately upstream of the transcription factor. Under which of the following conditions will the expression of target:gene "X" be induced?...
