PPT-Gene Regulation Part III

Mechanism of regulation of gene expression An overview Gene activity is controlled first and foremost at the level of transcription Much of this control is achieved through the interplay between proteins that bind to specific DNA sequences and their DNA binding sites .

To conserve resources, prokaryotes regulate their activities, producing only those genes necessary for the cell to function.@ . 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:. . Inter-locus Interactions. PBG 430. Locus. A. Allele A. Allele a. Locus. B. Allele B. Allele b. Phenotype. Inter-locus interactions . (Epistasis). Interaction(s) between alleles at different loci (i.e. interaction between genes). 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.
