Question

what term is used for a sudden,spontaneous change in gene?​

Answer 1

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.
