Unit 6 · 6.6 — Gene Expression and Cell Specialization [cite: 9, 10, 28]

Everything to learn here

• Concept: Multicellular organisms contain entirely identical genomic DNA in nearly all cells; complex tissue differentiation results purely from the cell-specific activation and repression of different distinct gene sets [cite: 10, 13].
• Concept: Differential gene expression, often influenced by small RNA molecules, determines the specific products and functions of different cells.
