Answer:
The correct answer is A) Histone deacetylation generally decreases gene expression.
Explanation:
Histones are the proteins that are responsible for the condensation of chromatin, which is directly linked to the capacity that a gene has to be expressed. The more condensed a gene is, the less expressible it becomes.
In order to regulate the gene expression, histones can suffer from many modifications that can change their conformation and the expressiveness of specific genes.
<u>Histone acetylation is linked with an increase of gene expression; while deacetylation and methylation decrease gene expression.</u>
Answer:
HbA; lowers
Explanation:
The BPG in our blood stands for Bisphosphoglyceric acid. It is known as by its name as 2,3-Bisphosphoglyceric acid. It is present in our blood in the red blood cells. It binds with more affinity towards the de-oxygenated hemoglobin as compared to the oxygenated hemoglobin.
Hemoglobin in blood delivers oxygen to our tissues moire efficiently. It is abbreviated as Hb.
Thus BPG binds more tightly towards HbA or adult hemoblobin and which lowers the affinity for oxygen.
