In genetics, a strain is said to be auxotrophic if it carries a mutation that renders it unable to synthesize an essential compound. For example, a yeast mutant with an inactivated uracil synthesis pathway gene is a uracil auxotroph (e.g., if the yeast Orotidine 5'-phosphate decarboxylase gene is inactivated, the resultant strain is a uracil ...
Formula One, abbreviated to F1, is the highest class of open-wheeled auto racing series administered by the Fédération Internationale de l'Automobile (FIA), motorsport's world governing body. [1] The "formula" in the name alludes to a series of rules set by the FIA to which all participants and vehicles are required to conform. [1] [2] The F1 ...
Indole-3-acetic acid (IAA, 3-IAA) is the most common naturally occurring plant hormone of the auxin class. It is the best known of the auxins, and has been the subject of extensive studies by plant physiologists. [1]
A selectable marker is a gene introduced into cells, especially bacteria or cells in culture, which confers one or more traits suitable for artificial selection.They are a type of reporter gene used in laboratory microbiology, molecular biology, and genetic engineering to indicate the success of a transfection or transformation or other procedure meant to introduce foreign DNA into a cell.

The CCAAT motif in plants (spinach was used in an experiment) differs slightly from metazoa in that it is actually a CAAT binding motif; the promoter lacks one of the two C residues from the pentameric motif, and the artificial addition of the second C has no significant effects on binding activity. Some sequences lack the CAAT-box completely.
The Gal4 transcription factor is a positive regulator of gene expression of galactose-induced genes. [1] This protein represents a large fungal family of transcription factors, Gal4 family, which includes over 50 members in the yeast Saccharomyces cerevisiae e.g. Oaf1, Pip2, Pdr1, Pdr3, Leu3. [2]
Saccharomyces cerevisiae, the yeast commonly used as baker's yeast. Gradation marks are 1 μm apart.. Baker yeast is the common name for the strains of yeast commonly used in baking bread and other bakery products, serving as a leavening agent which causes the bread to rise (expand and become lighter and softer) by converting the fermentable sugars present in the dough into carbon dioxide and ...
