Cancer-causing agents (carcinogens) usually act on dividing cells. Which of the four tissues would carcinogens most influence? Least influence?
Carcinogens can impact the genes and cause them to mutate in a negative way when they are introduced into the body. Before mitosis, the DNA generates a duplicate of itself, resulting in mutations. As a result, the DNA of the newly duplicated cell has a mutation. It's the birth of a cancer cell.
Because carcinogens affect cell division, they will stimulate, and accelerate, those tissues whose cells can divide. Connective tissue, as well as epithelial tissue, are suitable for tumor development because their cells divide, and carcinogens can act on the formation of epithelial and connective tissue tumors. On the other hand, muscle cells do not divide, they are mostly just hypertrophied, also nerve tissue cells do not divide. For this reason, muscle and nerve tissue will be least affected by carcinogens.
