They may design and perform an experiment to try to answer their question and test their hypothesis. From the results of their experiment, scientists draw conclusions.
Thats the way scientists think.
Answer:b
Explanation:
Heterogeneous mixture because it is not chemically bound together
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.
