The telomeres are the cell protectors occurring at the end of the chromosomes. It gets packaged into tightly condensed heterochromatin. Not only does it condense tightly, but also extends into the adjacent regions. It prevents the lethal fusions with other chromosomes and protects the chromosomes from the action of nucleases. It helps in responding towards the DNA damage. The model organism for studying the heterochromatin involves budding yeast. It shows epigenetic inheritance of heterochromatin. An important gene in the budding yeast involved in the inheritance of heterochromatin is known as the ADE2 gene. It encodes an enzyme involved in adenine biosynthesis. Loss of the gene activity leads to an accumulation of a red pigment. If the gene moves in the vicinity to the telomeric heterochromatin region, the gene expression gets silenced leading to the synthesis of red pigment. The inheritance of the red pigment-producing genes remains stable due to the stability of the heterochromatin.
