Explanation:
Detailed explanation-1: -External experiences spark signals between neurons, which respond by producing proteins. These gene regulatory proteins head to the nucleus of the neural cell, where they either attract or repel enzymes that can attach them to the genes.
Detailed explanation-2: -In the differentiation process, expression of pluripotent genes gradually decreases, while expression of differentiation marker genes increases. These temporal changes are a result of gene-gene regulation, which can be integrated as a GRN consisting of pluripotent and differentiation genes.
