What is the relationship between mutation, the cell cycle, and cancer? Select all statements that apply. A. Mutated genes typically allow cells to respond to checkpoint proteins that halt the cell cycle, thus avoiding formation of tumors.
B. As a result of unregulated cell cycles, cells may become cancerous, meaning that the cells grow and divide uncontrollably.
C. Cancerous cells may form malignant tumors that invade and destroy surrounding healthy tissue.
D. Mutated, defective genes may cause cells to become unable to respond to signals that regulate the cell cycle.

Why is a dominant allele called dominant

Charles darwin published his theory of evolution in 1859. in what way foes modern evolutionary theory differ from the theory as proposed by darwin? a) darwin inferred that individuals can evolve, but modern generic science has shown that this is not true. b)darwin inferred that individuals do not evolve, but modern genetic science has shown that this is not true. c)modern science has disproved most of darwin's original theory of evolution, because darwin knew nothing about generations and their role in heredity. d)generic studies have shown that gene expression and other factors operate along with natural selection, but most of darwin's theory has been supported by modern science.
