0

What affects whether a cell produces one protein or another?

Whether the genes are expressed (switched on)

1

What are totipotent cells?

Those which can mature into any body cell

2

How can gene expression be prevented?

By preventing transcription and breaking down mRNA before its genetic code is translated

3

What do cells lose once they have matured and specialised?

Their totipotency

4

What totipotent cells are still found in mature animals?

Adult stem cells

5

What are stem cells?

Undifferentiated cells

6

Where are adult stem cells found?

Bone marrow, small intestine and the skin

7

What other type of stem cells are there besides adult stem cells?

Embryonic stem cells

8

What are pluripotent cells?

Cells that can become multiple different types of cell

9

What are unipotent cells?

Cells that have a single function
