is the process by which genetic information from the DNA stored in the nucleus is transferred to the ribosomes where it is used to arrange amino acids into proteins. The DNA molecule in the nucleus is unzipped by an enzyme called polymerase. From one of these single strands of a DNA molecule, a mRNA molecule is built. Thi ....

.... the next amino acid. The mRNA thus transverses the ribosome with each three nitrogen base condon selecting an amino acid. This continues until the ribosome encounters a stop condon. When this happens the amino acid chain is released from the tRNA and is a protein. This process allows for the genetic information stored in the DNA to be expressed in the physical and functional makeup of the cell. ....
