Protein production/Secretion

Question 1

Stage 1

mRNA

Answer 1

A copy of a gene is made (called mRNA) in the nucleus

Question 2

Stage 2

Cytoplasm, nuclear pore

Answer 2

The mRNA moves into the cytoplasm through a nuclear pore

Question 3

Stage 3

Fuses, rough ER, protein synthesis

Answer 3

The mRNA fuses to the rough ER where protein synthesis occurs

Question 4

Stage 4

Vesicle

Answer 4

A vesicle breaks off from the rough ER, taking the protein with it.

Question 5

Stage 5

Fuses, Golgi

Answer 5

A vesicle Fuses to the Golgi apparatus.

Question 6

Stage 6

Modifies packages and delivers

Answer 6

The Golgi apparatus modifies, packages and delivers the protein.

Question 7

Stage 7

Vesicle

Answer 7

Another vesicle breaks off from the Golgi apparatus and goes to the cell surface membrane.

Question 8

Stage 8

Fuses, cell surface membrane

Answer 8

The vesicle fuses to the cell surface membrane

Question 9

Stage 9

Secreted (exocytosis)

Answer 9

The protein is secreted from the cell, this is called exocytosis.
