How many different amino acids in humans
20
What does the order of amino acids determine
Shape of protein
What does the shape of a protein determine
It’s function
The order of the proteins is determine by …
The sequences of bases in the gene for that protein
The cells read the DNA sequence in
Triplets 3
What does each triplet code for
The specific amino acid in the protein
Stages of protein synthesis
Transcription- the base sequence of the gene is copied into a complementary template molecule (mRNA)
mRNA passes out of the nucleus into cytoplasm
Translation - mRNA attaches to ribosome, amino acids are brought to ribosome on carrier molecules (tRNA) ribosome reads the triple of bases and joins amino acids in order
Once compete folds into unique shape
What does the shape of a protein determine
It’s function
