The correlation between micronuclei count and smoking behavior: a hospital-based study

J. oral res. (Impresa); 9 (2), 2020
Background: Micronucleus is a microscopically visible cyto-plasmic chromatin mass in the extranuclear vicinity, originating from aberrant mitosis, which consists of eccentric chromosomes that have failed to reach spindle poles during mitosis. The present study was designed to evaluate and compare cytogen...
