Glossary of cellular and molecular biology (0–L) in the context of "Overexpression"

This glossary of cellular and molecular biology is a list of definitions of terms and concepts commonly used in the study of cell biology, molecular biology, and related disciplines, including molecular genetics, biochemistry, and microbiology. It is split across two articles:

• Glossary of cellular and molecular biology (0–L) lists terms beginning with numbers and those beginning with the letters A through L.
• Glossary of cellular and molecular biology (M–Z) (this page) lists terms beginning with the letters M through Z.

This glossary is intended as introductory material for novices (for more specific and technical detail, see the article corresponding to each term). It has been designed as a companion to Glossary of genetics and evolutionary biology, which contains many overlapping and related terms; other related glossaries include Glossary of virology and Glossary of chemistry.
