Answer» Answer: Gene MUTATIONS cause a permanent ALTERATION in the sequence of base pairs (DNA-building blocks) that MAKES up a gene. Mutations can affect a single base pair or it can affect a larger segment, maybe even including multiple genes. When mutations are inherrited from a parent, they are present in almost every cell of the BODY. This in contrast with acquired mutations that can occur at any time in a persons life and are present in only in a subset of cells in the body. Acquired mutations can be caused by environmental factors such as ULTRAVIOLET radiation from the sun, or when a cell itself makes a mistake in copying its DNA during cell division. |
