James D. Watson, whose role as co-discoverer of the structure of the DNA molecule in 1953 made him one of the key figures in the rise of molecular biology as well as the obvious choice to be first ...

In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...

Life on Earth depends on the ability of cells to duplicate their genetic material, encoded in DNA molecules, and pass this information on to the next generation. Elucidation of the molecular mechanism ...

The Tactile DNA puzzle is a tool to teach visually impaired students the chemistry and structure of DNA. The puzzle contains the 4 different nucleotides (A,T,C,G) a phosphate piece and Deoxyribose ...
