|
|
||||
|---|---|---|---|---|---|
| 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
🗑
|
||||
| constitutive expression | show 🗑
|
||||
| show | genes coding for absolutely essential proteins that are constantly being expressed because they are always needed. not regulated
🗑
|
||||
| regulatory product | show 🗑
|
||||
| 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 🗑
|
||||
| activator | show 🗑
|
||||
| repressor | show 🗑
|
||||
| show | when gene expression is stimulated by the presence of an environmental signal
🗑
|
||||
| repressible | show 🗑
|
||||
| inducer | show 🗑
|
||||
| operon | show 🗑
|
||||
| promoter | show 🗑
|
||||
| show | common term for a regulatory element adjacent to the promoter. binding site for a regulatory product
🗑
|
||||
| show | cluster of co regulated genes involved in lactose metabolism
🗑
|
||||
| show | gene coding for Beta Galactosidase, the enzyme that breaks lactose into monosaccharides glucose and galactose
🗑
|
||||
| Lac Y | show 🗑
|
||||
| show | gene coding for trans acetylase
🗑
|
||||
| Lac I | show 🗑
|
||||
| show | regulatory product involved in positive regulation of lac operon and others as a response to glucose concentration
🗑
|
||||
| cAMP | show 🗑
|
||||
| show | a small RNA molecule that is the reverse complement of a normal mRNA. the two may hybridize, preventing translation by blocking the ribosomal binding site in prokaryotes
🗑
|
||||
| riboswitch | show 🗑
|
||||
| show | level of organization of a eukaryotic chromosome, euchromatin vs heterochromatin
🗑
|
||||
| acetylation | show 🗑
|
||||
| show | removal of an acetyl group
🗑
|
||||
| show | protein produced in female fruit flies that alters the splicing of the tra mRNA, producing a functional protein. males don't express sxl so tra mRNA is spliced in a different way, producing a nonfunctional protein
🗑
|
||||
| gal4 | show 🗑
|
||||
| show | repressor protein that blocks gal4 from making contact with the mediator, and therefore stops expression of the gal1 gene
🗑
|
||||
| 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
🗑
|
||||
| show | name given to the enhancer influencing gal1 expression
🗑
|
||||
| show | technique used to measure the amount of protein present by binding a specific protein with an antibody probe
🗑
|
||||
| show | technique used to measure the amount of RNA present by binding a labelled DNA probe to an RNA
🗑
|
||||
| primary antibody | show 🗑
|
||||
| show | immunoglobulin that recognizes the shape of a primary antibody. secondary is produced in large volumes to allow conjugation with other substances (enzyme, fluorescent compound, gold particle)
🗑
|
||||
| hybridization | show 🗑
|
||||
| microarray | show 🗑
|
||||
| show | enzyme used to convert RNA into its DNA coding sequence, cDNA. done to give a more stable molecule to work with in the lab instead of unstable RNA
🗑
|
||||
| reporter gene | show 🗑
|
||||
| transgenic organism | show 🗑
