Answer 2

Pluripotent cell

Question 3

Stem cells that could produce a limited range of cells

Answer 3

Multipotent

Question 4

Stem cells that would mature into a single type of cell

Answer 4

Unipotent

Question 5

True or False: Cells with the same genes will always have the same phenotype

Answer 5

False

Question 6

This mechanism for cell determination states that cell signaling mechanisms contribute the expression of genes

Answer 6

Inductive signalng among cells

Question 7

This mechanism for cell determination states that proteins and RNA are unequally segregated and that this contribute to the expression of genes

Answer 7

Asymmetric segregation of cellular determinants

Question 8

3 Major mechanisms of inductive signaling

Answer 8

Diffusion, Direct contact, Gap junction
