Cancers arise from a multistep process that involves the interplay of multiple changes, or mutations, in several different genes, in combination with environmental factors such as diet or lifestyle. Based on the relationship between genetic alterations and cancer development, please answer the following prompts: If mutated, what gene would lead to the proliferation of cells that survive when they should not? If mutated, what gene would lead to further mutations in other genes? Identify and describe each stage of multistage...

Bacterial cells, such as E. coli, are surrounded by a fluid plasma membrane and enclosed by a rigid cell wall that protects the cell from damage. You will recall that there is no nuclear envelope in prokaryotic cells, but rather a “nucleoid region” with a single chromosome that is continuous (circular), not linear, as in eukaryotes. All of the genes required for basic survival and reproduction are found in the main chromosome. In addition to the main chromosomes, some DNA...
