Two potential functions that eukaryotic cells perform to regulate transcription are DNA methylation: a process of epigenetics that participates in the regulation of the gene expression in two ways, directly impeding the union of the transcription factors, and indirectly propitiating the closed structure of the chromatin, and Histone acetylation, enzymes that acetylate conserved lysine residues in histones by transferring an acetyl group from an acetyl-CoA molecule, to form ε-N-acetyl lysine, is extensively associated with an open chromatin structure and therefore accessible to transcription factors, which increases gene expression.

Two Potenital Function

Following are the two potential functions that eukaryotic cells perform to regulate transcription as:

DNA MethylationHistone Acetylation

DNA methylation is a method through which methyl groups are combined with the DNA molecule. Methylation can alter the action of a DNA segment without adjusting the sequence. When positioned in a gene promoter then DNA methylation typically serves to repress gene transcription.

Histone acetylation is the method through which the lysine deposits in the N-terminal tail projecting from the histone core of the nucleosome are acetylated as a role of gene regulation. Histone acetylation is necessary parts of gene regulation.

Answer from: Quest

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

Listed in the item bank are some key terms and expressions associated with the categories seen in the venn diagram. to find out more information about items, some have more details available when you click on them. drag and drop each item onto the proper area of the diagram. if an item describes more than one category, be sure to place it in the overlapping space. viruses are tiny infectious pathogens that cause many different diseases, such as polio, and the flu. though they are similar to one celled organisms in some ways, in many ways they are very different. use the venn diagram below to show the similarities and differences between viruses and living organisms.
