When organic molecules decompose, energy is released.
fall & rise.. The initial compensating response to an acute respiratory alkalosis is a modest decline in ECF bicarbonate concentration as the result of cellular buffering. Subsequent renal responses result in decreased ECF bicarbonate concentration through reduced renal bicarbonate reabsorption.
Answer:
2. The white patches are caused by the deacetylation of the histones associated with the DNA of the w + allele.
3. The red patches are caused by the acetylation of the histones associated with the DNA of the w + allele.
Explanation:
The complete question is as follows:
How might one explain position-effect variegation in terms ofhistone acetylation and/or deacetylation? Select all thatapply.
1. The white patches are caused by the acetylation of the histonesassociated with the DNA of the w + allele.
2. The white patches are caused by the deacetylation of thehistones associated with the DNA of the w + allele.
3. The red patches are caused by the acetylation of the histonesassociated with the DNA of the w + allele.
4. The red patches are caused by the deacetylation of the histonesassociated with the DNA of the w + allele.
In the W+/W State variegated eye is produced, however in reality the W+ allele causes a red eye colour whereas the W allele causes a white eye.
The reason for production of variegated eyes is chromosomal rearrangement.
Due to the chromosomal rearrangement the W+ gene's position gets changed and it moves from a region of euchromatin to heterochromatin and this position affect leads to red and white patches in the eye.
The heterochromatin is silent region of the genome which does not encode for any product and this is caused by histone deacetylation whereas the histone acetylation makes the chromosomes more accessible and contributes the euchromatin region.
The molecule known as coenzyme A plays a key role in cell metabolism by regulating the actions of nitric oxide. Coenzyme A sets into motion a process known as protein nitrosylation, which unleashes nitric oxide to alter the shape and function of proteins within cells to modify cell behavior.
