|
||||
|---|---|---|---|---|---|
| show | some substance in the environment responsible for triggering a change in gene expression. Could be chemical substance, radiation, temperature, pH, or environmental condition
🗑
|
||||
| show | gene that is coding for a metabolic enzyme or protein used to build a structure
🗑
|
||||
| show | genes that are always being expressed, and therefore not regulated, are constitutively expressed
🗑
|
||||
| housekeeping genes | show 🗑
|
||||
| show | protein or RNA that influences the expression of other genes by binding to the regulatory element. may influence transcription or translation. trans acting
🗑
|
||||
| show | nucleic acid sequence (DNA or RNA) which the regulatory product attaches, influencing the expression of genes physically connected to the element. cis acting
🗑
|
||||
| show | when a genes expression is stimulated by binding of regulatory product to the regulatory element, but expression is turned off when they do not bind
🗑
|
||||
| negative control | show 🗑
|
||||
| show | a regulatory product responsible for positive control
🗑
|
||||
| repressor | show 🗑
|
||||
| show | when gene expression is stimulated by the presence of an environmental signal
🗑
|
||||
| repressible | show 🗑
|
||||
| inducer | show 🗑
|
||||
| show | system of regulation common in prokaryotes. involves multiple genes coding for proteins involved in the same biochemical process sharing a single promoter and regulatory element. when one gene is expressed all are expressed. produces a polycistronic mRNA
🗑
|
||||
| promoter | show 🗑
|
||||
| show | common term for a regulatory element adjacent to the promoter. binding site for a regulatory product
🗑
|
||||
| lac operon | show 🗑
|
||||
| Lac Z | show 🗑
|
||||
| show | gene coding for permease, transporter protein used to move lactose into the interior of the cell from the external environment
🗑
|
||||
| Lac A | show 🗑
|
||||
| Lac I | show 🗑
|
||||
| catabolite activator protein (CAP) | show 🗑
|
||||
| cAMP | show 🗑
|
||||
| antisense RNA | show 🗑
|
||||
| riboswitch | show 🗑
|
||||
| chromatin structure | show 🗑
|
||||
| acetylation | show 🗑
|
||||
| show | removal of an acetyl group
🗑
|
||||
| sex lethal (sxl) | show 🗑
|
||||
| gal4 | show 🗑
|
||||
| gal80 | show 🗑
|
||||
| show | repressor of the repressor gal80... therefore an activator. prevents gal80 from blocking contact between gal4 and the mediator. responds to galactose concentration as an environmental signal
🗑
|
||||
| upstream activation sequence (UAS) | show 🗑
|
||||
| western hybridization | show 🗑
|
||||
| show | technique used to measure the amount of RNA present by binding a labelled DNA probe to an RNA
🗑
|
||||
| show | immunoglobulin that recognizes the 3d shape of a protein (epitope) and is able to bind
🗑
|
||||
| secondary antibody | show 🗑
|
||||
| hybridization | show 🗑
|
||||
| microarray | show 🗑
|
||||
| reverse transcriptase | show 🗑
|
||||
| show | gene whose protein product is easily detectable (enzymatic reaction, light production etc). often attached to regulatory element and used to make transgenic organisms to identify where expression of a gene would normally occur
🗑
|
||||
| transgenic organism | show 🗑
