DNA is the same in every cell in the body. They all read from the same genetic blueprint, whether they are muscle cells, skin cells, or heart cells.
it is Because they use the same set of genes in different ways, and these cells are different. So despite the fact that every one of our cells has the equivalent of 20,000 or so genes, every cell can choose which ones it needs to "turn on" and which ones it needs to keep "turned off. heart cells have unexpected attributes in comparison to skin cells since heart cells express unexpected genes in comparison to skin cells.

B. when the immune system attacks the body's own cells
Solution:
Cell-division control affects many aspects of development. Caenorhabditis elegans cell-cycle genes have been identified over the past decade, including at least two distinct Cyclin-Dependent Kinases (CDKs), their cyclin partners, positive and negative regulators, and downstream targets. The balance between CDK activation and inactivation determines whether cells proceed through G1 into S phase, and from G2 to M, through regulatory mechanisms that are conserved in more complex eukaryotes.
This is the required process through phosphorylation, Cdks signal the cell that it is ready to pass into the next stage of the cell cycle. As their name suggests, Cyclin-Dependent Protein Kinases are dependent on cyclins, another class of regulatory proteins. Cyclins bind to Cdks, activating the Cdks to phosphorylate other molecules.
Answer: Aorta
Explanation: The aorta is the largest artery in the body. It carries oxygenated blood from the left ventricle of the heart into systemic circulation. The aorta has many subdivisions that branch off into smaller arteries.
