B 2.3 Cell Specialization

Question 1

How does differentiation between cells occur?

Answer 1

All cells in an organism have the SAME DNA and different expressions of the genes- some being on and others off depending on the type of cell

Question 2

what is cell signaling

Answer 2

the transfer of information from one cell to another’s surface and then into it’s nucleus

Question 3

What are morphogens and their functions?

Answer 3

Morphogens are signaling molecules that occur in gradients (areas of concentration differences)

Question 3

What is the impact of gradients on gene expression within early-stage embryos?

Answer 3

the gradients control the cells into a head and tail, which then result in different genes being expressed in different parts of the embryo, and it’s further development.
