Differentiated cells have the same DNA (genome) as all other cells in an organisms.

Cells differentiate when specific genes (sections of DNA) are activate through protein synthesis (transcription and translation)

Factors that affect cell differentiation

• External Stimuli (e.g., temperature, chemicals, radiation, diet)

• Internal Stimuli (e.g., enzymes, non-coding RNA, hormones)

• Signals from other cells in the organisms (e.g., proteins and other signaling molecules)
