One of the basic tenents of Biology is that DNA, found in the nucleus of every cell, is translated by RNA and codes for proteins that build and carry out the functions of life. In this video (brought to me by LinkedIn) you can see it happen via animation. http://www.youtube.com/watch?v=9kOGOY7vthk
Gladstone scientists map process by which brain cells form long-term memories. Great discoveries are not made all at once, but rather in little steps, one at a time. One such little step seems to have uncovered the pathway by which learning goes from temporary into long-term storage, thus establishing new pathways in the brain long into adulthood.
