fertile soil contains more amount of water as compared to barren or infertile soil..
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.

Answer:
C.) 26 - 13
Explanation:
During mitosis, DNA is replicated during the S phase so that when the cell divides the daughter cells will have the same number of chromosomes that the parent cell had.
DNA replication also occurs during meiosis, but the cell divides twice, so the daughter cells will have half the number of chromosomes that the parent cell had. This is because the daughter cells are sex cells, which combine with another sex cell (either an egg or a sperm) to form one cell with a combined chromosome number.

C
