BB 2920 Genetics A term 2011 Problem Set 1 Due Thursday, September 1, 2011 by 2:00. You will turn in the Problem Set via the test function on the web site, which will be posted on Monday. Always choose the best or most likely explanation for the problem posed. Some of the other answers may be remotely possible, but you should always choose the most reasonable answer. Also, some answers may be true, but may not completely explain the data. Be sure to think through all the possible answers. For crosses, I suggest writing out the cross that is described before answering the question. Each question is weighted the same, even if a problem is subdivided. So for example, question 5A is worth the same number of points as question 1.

Regulation of gene expression is important because a) Different cell types need to have different genes expressed b) Different genes need to be turned ‘on’ and ‘off’ during embryogenesis c) Cells need to be able to respond to damage or disease agents d) Cells need to have all of their genes ‘on’ (expressed) at all times 4) Gene regulation occurs through a) Transcription factors binding to promoters or enhancers b) Transcription factors binding to exons c) Promoters binding to exons d) Promoters binding to enhancers e) a) or d)
