structure?

Answer 11

Integrin + PAF-receptors

Answer 13

Cytosol

Question 14

Where are proteins transported from ER during protein maturation?

Answer 14

Cis-Golgi

Question 15

During in vitro motility assay?

Answer 15

Myosin attached to the glass

Question 16

The researchers identified the complex process of protein secretion on?
