Pleistocene age also knwon as the Ice age. Thereafter, there are many accounts that happened that lead to global warming. One that is true is Global warming began 18,000 years ago as the earth started warming its way out of the Pleistocene Ice Age, B is also correct as well. Forests have also returned but sea levels in fact rose to about 300 feet. Answer then is C.
Answer:
Phosphorylation
Methylation
Explanation:
Histone mobilization deals with the covalent bonding of several functional groups to the free nitrogens in the R-groups of lysine in the N-terminal tail.
DNA transcription can be controlled or altered via 'methylation' on the histones. Methylation is the mode of transferring methyl group to amino group of histone proteins that form the nucleosomes, which result to chromosomes formation through wrapping of DNA double helix around it. Histones methylation can either increase or decrease genes transcription. Chromatin modification is known to stimulate neural pathways that are essential for long memories and learning.
Histones phosphorylation is associated transcriptional activation. It deals with the transfer of phosphate group to amino acids of the proteins. Phosphate group known to be negatively charged, when transferred to amino acids of the histone proteins, it creates a repulsive force with the negatively charged phosphates of the DNA backbone. It can occur in serine, tyrosine and threonine. The enzymes kinases activate phosphorylation, while protein phosphatases remove phosphate groups.

The nucleus is able to control and regulate the rest of the cell(it basically tells it what to do). The DNA is made up of chromosomes,the DNAs shape is a double helix and is tightly packed inside of the nucleus. The job of the DNA is to regulate the rest of the cell and tell the cell what kind of cell it is and what job it needs to do(ex all cells are different so the dna determines the type of cell like a bone cell or blood cell) this ties in with genetic because your dna makes up your cells and your cells make up who you are.
