Comprehension Questions

What primary effect did the discovery of iPSCs have on the concept of cellular development?

It confirmed that adult cells can only ever differentiate into more specialized cell types.

It established that embryonic cells are the only source of pluripotent material.

It proved that cellular development can be a two-way street where adult cells can return to an embryonic-like state.

Reveal Answer

✓

Correct Choice

It proved that cellular development can be a two-way street where adult cells can return to an embryonic-like state.

What is one major ethical advantage of using iPSCs?

They are cheaper to mass-produce than any other cell type.

They do not require any laboratory facilities to be cultivated.

They provide pluripotent cells without the need for human embryos.

Reveal Answer

✓

Correct Choice

They provide pluripotent cells without the need for human embryos.

Why is personalized medicine a key benefit of iPSC technology?

Because they allow for the immediate synthesis of new human organs.

Because they are derived from a patient’s own cells, minimizing the risk of immune rejection.

Because they eliminate the need for doctors to diagnose patients.
