Abstract

The centromere functions are conserved among all eukaryotes but different organisms have strikingly different centromeric deoxyribonucleic acids (DNAs). Currently in molecular terms, the functional centromere can be defined as a domain of the chromosome where DNA sequences interact with the kinetochore components – proteins. A fundamental feature of all the studied centromeres is a specialized histone H3 variant known as centromeric histone (CENH3). Adaptive evolution of the molecular components contributed to the epigenetic modulation of centomere activity.
