molecules

Protein Synthesis…

NucleusHold DNA for protein

NucleolusMake mRNA copy of gene

Nuclear EnvelopeMoves mRNA out through

pores

Rough ERTransport- mRNA attaches

to its ribosome

Ribosomes‘Read’ code on gene and

uses to make protein

GolgiProcess and packages

protein into vesicles, they pinch off into cytoplasm

Cell Surface Membrane

Vesicle attaches to this, releasing protein outside

cell

EukaryoticPlasma membrane

Linear DNA- nucleus
