Step 1 : Introduction to the question "which of the following is not a feature of the dna helix proposed by watson and crick?"
...A. double-stranded B. right-handed C. antiparallel D. complementary base pairing E. two grooves of equal dimensions. Concept 19 The DNA molecule is shaped like a twisted ladder. James Watson and Francis Crick solved the structure of DNA. Other scientists, like Rosalind Franklin and Maurice Wilkins, also contributed to this discovery. It's commonly believed that James Watson and Francis Crick discovered the double helix shape of DNA. But in fact, they based their work on one of their colleagues at King's College in London - Rosalind Franklin, an x-ray diffraction expert whose images of DNA proteins in the early 1950s revealed a helix shape.It's commonly believed that James Watson and Francis Crick discovered the double helix shape of DNA.
