During the transition from euchromatin to heterochromatin, gene expression is suppressed. This suppression is achieved through molecular mechanisms such as DNA methylation, which involves the addition of methyl groups to DNA, and histone deacetylation, which leads to the removal of acetyl groups from histones. These modifications create a more compact and less accessible chromatin structure, inhibiting gene transcription.

Option 1 is the correct answer.
