Any agent (physical or environmental) that can induce a genetic mutation or can increase the rate of mutation
A change in genetic material
Controls what goes in and out of the nucleus

Describes a cell that does not have a nucleus or any other membrane-covered organelles; also called bacteria.
A cell characterized by the presence of a nucleus and other membrane-bound organelles. Eukaryotes can be unicellular (protists) or multicellular (fungi, plants and animals).
A cell organelle constructed in the nucleolus and functioning as the site of protein synthesis in the cytoplasm; Consists of rRNA and protein molecules, which make up two subunits.
