Malignant Cancers Often Require That a Single Cell Experience as Many

question 92

Multiple Choice

Malignant cancers often require that a single cell experience as many as four mutations; does a single mutation predispose a cell to a second or third?

• A)Yes, particularly if the first mutation depresses a DNA-correcting mechanism allowing subsequent injuries to remain uncorrected.
• B)No, each cell is uniformly at risk for mutation; if a cell has four mutations, it likely that its neighbors have two or three.
• C)Yes, initial mutations often lead to the construction of carcinogen receptors that pull harmful chemicals into the cell and accelerate the mutation process.
• D)No, mutation is an entirely random process; carcinogens have no way of locating a previously damaged cell.
