Protein synthesis

The second stage of protein synthesis, translation, involves the ‘translation’ of the sequence of bases on mRNA into a sequence of amino acids in a protein.

The bean-shaped ribosome binds to mRNA (the long purple/pink strand) and binds triplet of tRNA bases that correspond to the bases on the mRNA. The tRNA is bound to amino acids that are strung together to construct the first form a protein molecule takes. The protein synthesis system has two stages: transcription and translation. Transcription is the process whereby the DNA is transcribed into the form known as mRNA that gets transported out of the nucleus. The second stage, translation is the process where the mRNA is ‘translated’ into a protein.
