This part-colored handout is a holistic guide that maps out the central dogma of biology. It shows the location of DNA in the nucleus of a cell. It shows RNA polymerase unzipping and copying DNA in transcription. It pictures m-RNA leaving the nucleus and later being translated in the ribosome in the cytoplasm of the cell in translation with the help of t-RNA. This document shows the codons matching up with the anti-codons in the ribosome. It references the growing polypeptide protein chain of amino acids. This guide points out that the product of translation will become a structural protein, a carrier protein, a hormone, an antibody, or an enzyme. The bottom third of this handout depicts the enzyme lactase with a labeled active site fitted for the substrate molecule lactose next to it. Alongside lactose is a similar shaped labeled competitive inhibitor molecule. The two primary factors that denature proteins are illustrated and identified too - extremely low pH and extremely high temperatures. In the event you are wondering, the thumbnail image distorted the layout of my document.
