DNA encodes amino acids of a protein using 3 letter codons.
DNA is transcribed to make mRNA.
mRNA is translated by ribosomes to make the protein.
Figure 2. Bacterial Protein Synthesis.
Eukaryotic protein synthesis is more complex than prokaryotic!!
Eukaryotic DNA is transcribed to make a pre-mRNA, then the pre-mRNA is processed.
Processing removes the intervening sequences found in eukaryotic DNA, which are called Introns.
During Processing, the Exons containing the coding region for the protein are joined.
Also some modifications of the ends of the mRNA are made and it goes into the cytosol.
In the cytosol, ribosomes translate the mRNA to make protein in manner very similar to prokaryotes.
