Protein Synthesis

     Protein Synthesis begins with the stored genetic information in the DNA module. In the process of Protein Synthesis, only one side of the DNA is used. RNA molecules come in and fill in as the other half of the DNA. When this process is finished, the DNA closes back together with the other half strand leaving half a strand of messenger RNA (mRNA). The mRNA will leave the nucleus and travel to a ribosome to construct a protein molecule.

The mRNA creates segments of three for the transfer RNA (tRNA) to land on. Each of the segments has a code for each type of amino acid that lands on it. The tRNA will have the different types of amino acids that will combine into many strands that create proteins. All the amino acids are then linked by a peptide bond. After that, the tRNA leave the ribosome and the same process will repeat itself until it gets a strand of different amino acids. A short strand of amino acids are called polypeptides and of the long ones are all called proteins.

Your body needs these proteins to build muscle. Proteins also contain alot of amino acids like L-Lysine. L-ysine is the amino acid that makes grow at night. Proteins also help build cardiac muscle that helps keep the heart beating. Whithout that muscle, you'd be as dead as your great great great great grampa.
