Answer:
The correct answer will be option- A.
Explanation:.
Histone demethylases are the enzymes which controls the gene expression of any gene. These enzymes play an important role in epigenetic control of gene. The post-translational modifications like methylation and acetylation changes the structure of the chromatin which alters the interactions of the chromatin.
The histone demethylase removes the methyl group from the histone tails which causes the condensation of the loose chromatin structure to form heterochromatin.
Thus, option-A is the correct answer.
The raw materials of H2O and CO2 are located there
35. The paragraph at the top of the page tells you "Catalase [is] a biological catalyst produced by cells [that] speeds the breakdown of hydrogen peroxide."
Of course, you know that, in general, a catalyst is a substance that facilitates a chemical reaction without being used up as a result of that reaction.
36. Catalase is most active at the temperature of 35 °C. (This is not unexpected, as 35 °C is near the temperature considered to be normal body temperature (37 °C).) The table and the corresponding graph show this to be the case.
