This chapter focuses on regulation and regulatory processes overlap. consist of a promoter, operator, and a cluster of genes that control a common pathway, operon that is normally on because the repressor is inactive, operon that is normally off because the repressor is active, DNA sequence that codes for a functional protein, a segment of DNA near the promoter region that acts as an on or off "switch", a protein that binds to the operator to switch an operon off, inactivates the repressor (turns on the operon), codes for the production of the repressor protein; found upstream of the operon, works with the repressor to turn off the operon, caused by variations in gene expression; leads to cell specialization in structure and function, the process of acetyl groups attaching to histone tails (opens up chromatin structure), adding methyl groups to cytosine during replication (tighter coiling and thus inactivation of genes and reduced transcription), short segments of DNA upstream from a gene that increase the likelihood of transcription, a specific protein that binds to an enhancer region to stimulate gene transcription, some act as repressors by blocking the binding of activators or binding to an enhancer, the phenomenon of gene silencing by non-coding RNA molecules, an enzyme that links ribonucleotides into a growing RNA chain during transcription, small RNAs that work with one or more proteins to prevent translation by binding to a wide range of mRNAs using a handful of bases, small RNAs that work with one or more proteins to prevent translation by cbp to a specific mRNA, a normal cellular gene that has the potential to become an oncogene, a gene whose protein product inhibits cell division thereby preventing the uncontrolled cell growth that contributes to cancer, use of repressors to control gene expression, use of activator molecules to increase gene expression, concentration of substances present in cell either inhibits or activates expression, lac operon; result is production of proteins that cause degradation of lactose - but only if lactose is present, trp operon; causes cell to make tryptophan if it is absent, DNA coiled around proteins; makes transcription harder, heritable changes caused by the activation and deactivation of genes without any change in the underlying DNA sequence of the organism, produces different mRNA molecules when different segments of the mRNA are chosen as introns or exons.
