Protein Synthesis information and stages Flashcards
What are proteins made out of?
Proteins are made out of amino acids joined together (polypeptide chain)
What are amino acids
- They are small molecules
- There are only 20
The molecule use to take the message from the DNA to the ribosome is called
mRNA
Where do proteins start
Protein starts off at the ribosome as a single chain called polypeptide
Stage 1
DNA never leaves the cells so the nucleus so it must make an exact copy of its self
Stage 2
DNA unwinds opens up and splits into two strands
Stage 3
Messages RNA (mRNA) is then made against a DNA strand and then passes out of the nucleus into the cytoplasm.
Stage 4
The complementary code from the DNA carried out on the mRNA moves to where the protein is assembled from amino acids.
