micronucleus
biology
Quick Summary
A micronucleus is a minute nucleus, specifically one involved in reproductive and genetic functions within certain protozoans. In ciliate protozoans, such as Paramecium, a macronucleus is also present and influences many cell activities. The macronucleus is typically associated with one or more smaller micronuclei, which are essential for reproductive processes like conjugation and autogamy. During these reproductive events, the macronucleus degenerates and is later re-formed from nuclear material in the zygote.12
