CHALK TALK: DNA

submitted by: nsf

DNA contains the genetic code used by all known living organisms. It also contains historical information, because it collects “mistakes,” called mutations, over time. DNA is a building block too--it has the ability to self-assemble into complex structures.

Visual method for representing five DNA and RNA bases U C A G T with five discrete values on the gray-scale: black (100%), dark (75%), gray(50%), light (25%) and white(0%) www.visualDNA.org This animation illustrates a proposal to replace the nucleic bases letter representation with five discrete values on the gray scale. Instead of letters UCAGT this concept employs five discrete values U=Black, C= Dark, A=Gray, G=light, and T= White. Value of "black" is defined as "absence of light",...

Special cases are icons with equal numbers of the two bases (for example 6xG and 6xC). In these cases an icon has high organization if bases C ocupies one its halves and G...

Protein Synthesis

submitted by: jmath

A demosntration of Protein synthesis expressed through dance. The film was directed in 1971 by Robert Alan Weiss for the Department of Chemistry of Stanford University and narrated by Paul Berg, a 1980 Nobel Prize winner for Chemistry. It is imprinted with the "free love" aura of the period, and continues to be shown in biology classes today. It has inspired a series of similar funny attempts at vulgarizing protein synthesis.
