Environment cues activate what type of proteins to influene gene expression?

Expert Solution

Environmental cues is defined as a signals for action, that specific portion of a field or pattern of stimuli to which the subject has learned to respond.

There are several environmental cues which influence the gene expression, like:

TEMPERATURE : A study made on the wings of drosophila with response to temperature provided results with the effect of temperature. Flies exposed to the temperature of 25 degree Celcius showed less penetrance whereas flies exposed to higher temperatures showed increased penetrance. This was observed the increase in development of wings in the selected population of flies.

LIGHT : The plant carrying the homozygous gene for pigmentation develops a bright red color when exposed to sunlight. But when the sunlight is restricted or if the plant that is prone to pigmentation is croverd from sunlight, the bright red color pigment was not observed.

NUTRITION : The deficient nutrient alters gene expression. For example, whatever the pregnant woman eats determines the health of her offsprings. The folic acid supplement takes care of the development of the fetus whereas the the deficiency of folic acid leads to birth abnormalities.

Global regulators are proteins that can repress or activate the expression of large numbers of genes in an organism. A recent report describes structural studies on the anti-repressor AbbA from the bacterium Bacillus subtilis [Tucker et aL, J. Mol. Biol. (2014)]. This protein has the ability to bind to a second protein, a global repressor named AbrB. These researchers first characterized their recombinant version of AbbA, a 65-residue protein prepared in E.coli cells. (Qa).During the isolation and purification of AbbA,...

Genomic control: What is the aspect or type of gene expression control event described; a) The methylation of cytosines in a DNA promoter region prevent transcription factors from binding at a promoter. And acetylation of histones to make a region of DNA more available for transcription are both forms of this type of control: b) Xenopus laevis, normally contains about 500 copies of ribosomal RNA genes, but during oogenesis that number expands to about 2 million due to egg development...

In combinatorial transcriptional regulation, expression of a particular gene in a specific cell type is controlled by Select one: a. the combination of enhancers present in that cell type. b. the combination of transcription factors present in that cell type. c. the requirement of the gene for the cell’s function. d. the presence or absence of RNA polymerase in the cell. In eukaryotic genes, enhancer sequences are usually found Select one: a. close to the promoter region of the gene....
