How does the transition from euchromatin to heterochromatin impact gene expression?
It activates gene expression.
It suppresses gene expression.
It has no effect on gene expression.
It depends on the type of chromosomal proteins present.
Euchromatin is considered transcriptionally active chromatin, while heterochromatin is inactive. Therefore, the transition from euchromatin to heterochromatin typically leads to the suppression of gene expression.Hence, option 2 is the correct answer.
