  8. Basic Rules of Protein Folding

    31 Dec 2008 | | Contributor(s):: Seth Lichter

    How are proteins made? Inside cells, messenger RNA first instructs the ribosomes as to the order which amino acids should be joined together. Linked together and released from the ribosome, the protein is not functional. It now needs to fold into a precise three-dimensional shape. There are no...
