During differentiation of stem cells into a specific tissue type, epigenetic regulation is critical mainly because:
Show answer and explanation
Correct answer: It silences or activates gene sets for that cell type, not the sequence
Epigenetic regulation enables stable activation of lineage-specific genes and silencing of irrelevant ones by altering chromatin structure, allowing differentiation without changing the nucleotide sequence.
