MICRONUCLEUS TESTS Meaning and
Definition
-
Micronucleus tests refer to cytogenetic assays used to evaluate the presence of micronuclei in cells, particularly in the nucleus. Micronuclei are small, additional nuclei that form during cell division as a result of chromosomal damage or abnormalities. This testing method is commonly employed in genotoxicity and mutagenicity studies to assess the potential harmful effects of various physical and chemical agents on the genetic material and chromosomal integrity.
The micronucleus test involves collecting cells (often blood or buccal cells) from an individual or an organism and preparing slides or cultures to examine the presence of micronuclei. The cells are stained and examined under a microscope to identify any extra micronuclei in addition to the main nucleus. These micronuclei are often evaluated for size, shape, and any chromosomal abnormalities present. The frequency of micronuclei is then recorded and can be correlated with the exposure level of a specific agent to assess its genotoxic potential.
Micronucleus tests provide valuable information on the likelihood of an agent causing genetic damage, including chromosomal breakage, loss, or rearrangement. By assessing the frequency and characteristics of micronuclei, scientists can make informed decisions regarding the safety or potential hazards associated with certain substances or environmental factors.
Overall, micronucleus tests are essential tools in toxicology and genetic research, aiding in the determination of genotoxic effects and the potential risk to human health posed by various agents.

Etymology of MICRONUCLEUS TESTS
The word "micronucleus" originates from the combination of two terms: "micro" and "nucleus".
- "Micro" comes from the Greek word "mikros", meaning small. It is commonly used as a prefix in scientific terminology to refer to something very small in size or scale.
- "Nucleus" is derived from the Latin word "nucleus", meaning the central part or core. In biology, it typically refers to the central structure within a cell that contains genetic material.
The term "micronucleus" specifically refers to a small nucleus (structure) within a cell.
The word "tests" in "Micronucleus Tests" simply represents the plural form of the word "test", which in this context refers to scientific investigations or procedures conducted to evaluate and study micronuclei within cells.
