Answer:
undergo irreversible repression
Explanation:
Cellular differentiation refers to the process by which one cell and/or cell population divides and differentiates into more specialized cells. During cell fate differentiation, epigenetic marks modify chromatin structure in order to hamper the accessibility of the transcriptional machinery and transcriptional factors to different genes, which are irreversibly repressed. These epigenetic marks include DNA methylation and histone modifications (e.g., histone acetylation, histone methylation, etc). For example, it has been shown that DNA methylation and histone H3 lysine 27 tri‐methylation (H3K27me3) are epigenetic repressive marks on genomic regions that play a major role in gene expression programs during cell fate differentiation.
Answer:
If four samples have the same volume, the sample with the highest mass will have the highest density, i.e. sample Z.
Explanation:
The density expresses the amount of mass that occupies a given volume, and knowing the mass and volume of a solid, the density can be determined by the formula:
<em> ρ = m/V
</em>
From this formula it can be determined that <u>density is directly proportional to mass and inversely proportional to volume</u>.
Of the four samples, the highest mass is in the sample Z (312), so this sample has the highest density.
