Cell differentiation

Which cells in your body have the same DNA?

• Nerve and germ cells

• All somatic cells in every human on earth

• Germ cells and muscle cells

• All somatic cells in one person's body

How is it possible that liver cells and eyeball cells have the same DNA?

• The nerve cells make the liver and eyeball cells

• Liver cells can turn into eyeball cells

• Eyeball cells can turn into liver cells

• Both liver and eyeball cells originally came from the same first cell

What is an embryonic stem cell?

• A stem cell present in the body after the organism has become an adult

• An unspecified cell in an embryo that can turn into any type of somatic cell

• An unspecified cell in the body present after birth

• A specific type of somatic cell, such as a skin cell or a muscle cell

What is cell specialization or differentiation?

• The process where unspecialized cells become different in structure and function.
• When DNA controls the cell cycle.
• The ability of cells to make more cells.
• The ability of cells to maintain homeostasis.
