EVERYDAY SCIENCE

Detailed explanation-1: -The chemical or physical agents that cause mutations are called mutagens. Examples of physical mutagens are ultraviolet (UV) and gamma radiation. Radiation exerts its mutagenic effect either directly or by creating free radicals that in turn have mutagenic effects.

Detailed explanation-2: -A mutagen is a chemical or physical agent capable of inducing changes in DNA called mutations. Examples of mutagens include tobacco products, radioactive substances, x-rays, ultraviolet radiation and a wide variety of chemicals.

Detailed explanation-3: -(MYOO-tuh-jen) Anything that causes a mutation (a change in the DNA of a cell). DNA changes caused by mutagens may harm cells and cause certain diseases, such as cancer. Examples of mutagens include radioactive substances, x-rays, ultraviolet radiation, and certain chemicals.

Detailed explanation-4: -Chemical mutagenesis and enzymatic misincorporation techniques cause a small number of mutations throughout a piece of DNA. Both methods yield a library of mutations that are cloned into a plasmid and then screened or selected for function. Commonly used chemicals include sodium bisulfite, formic acid, and hydrazine.
