ixteen strands of DNA, stacked four-by-four, form the beam-shaped chassis of the DNA motor (in gray). Bits of DNA (in green) protrude from the chassis like little feet. The motor is fueled by RNA ...

At King's College in London, Rosalind Franklin and Maurice Wilkins were studying DNA. Wilkins and Franklin used X-ray diffraction as their main tool -- beaming X-rays through the molecule yielded ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding ...
