What is a micro nucleus?
Understand the Problem
The question is asking for a definition or explanation of what a micro nucleus is, likely in a biological or cellular context.
Answer
A micronucleus is a small nucleus from fragments or entire chromosomes left outside the main nucleus post cell division.
A micronucleus is a small nucleus formed by chromosome fragments or entire chromosomes that remain outside the main nucleus after cell division. It may result from DNA damage or issues during DNA replication.

A micronucleus is a small nucleus formed by chromosome fragments or entire chromosomes that remain outside the main nucleus after cell division. It may result from DNA damage or issues during DNA replication.
More Information
Micronuclei can indicate exposure to clastogenic agents, which cause breaks in chromosomes. They serve as important biomarkers in environmental and genetic studies.
Tips
A common mistake is confusing micronucleus with ciliate protozoans' nucleus which also has the term 'micronucleus'. Ensure the context relates to cellular biology and genetic study.
