Research in molecular biology is . CSCOPE. Unit: 08 Lesson: 01. There are hundreds of different types of cells in your body, and each type has a unique function. We’re going to compare some different types of cells to see how much they have in common. . Draw 8 boxes on your paper. Gene regulation accounts for some of the phenotypic differences between organisms with similar genes.. 2005-2006. Gene regulation in bacteria. Control of gene expression enables individual bacteria to adjust their metabolism to environmental change. The cerebellum is the region of the brain that coordinates motor control, and many human neural disorders impact the cerebellum.. Several spontaneous mouse mutants with motor defects have been found, including:. Gene Regulation Gene expression can be turned on, turned off, turned up or turned down! For example, as test time approaches, some of you may note that stomach acid production increases dramatically&# (Chapter 9). Presented by Dr. Laurie M. Erickson.
