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",...
