If you were able to look very closely at a portion of dna and find methylated histones, you would be looking at a region of inactive chromatin.
- Histone methylation is the process by which methyl groups are added to the histone protein amino acids, which create the nucleosomes around which the DNA double helix coils to form chromosomes.
- Histone methylation is the addition of one, two, or three methyl groups to certain amino acids within a histone protein. Histones are coiled around DNA in the cell nucleus.
- These findings collectively imply that DNA methylation can be either active—as a probable contributor to levels of gene expression variation—or passive—as a result of or a separate indicator of gene expression levels.

The answer should be "His observation of the geographic distributions of living things."
[ Equilibrium / Diffusion ] is the simplest type of passive transport. 7. The diffusion of water through a selectively permeable membrane is called [ osmosis / diffusion ].
They are called CHNOPS elements which stands for Carbon, Hydrogen, Nitrogen, Oxygen, phosphorus, and Sulfur
Answer:
C
Explanation:
A is wrong: making lipids is the SMOOTH ER's job, not the rough er
B is wrong: protecting the nucleus is the nuclear membrane's job
D is wrong: Producing ATP is mainly the mitochondria's job
C is right because the ribosome's main job is making proteins, and those instructions come from the nucleus, so there needs to be a close access.
