WebA major landmark was attained in 1953 when American geneticist and biophysicist James D. Watson and British biophysicists Francis Crick and Maurice Wilkins devised a double helix model for DNA structure. Their breakthrough was made possible by the work of British scientist Rosalind Franklin, whose X-ray diffraction studies of the DNA molecule shed … WebDNA is made up of two strands that are twisted around each other to form a helix. Adenine pairs up with thymine and cytosine pairs with guanine. The two strands are antiparallel in nature; that is, the 3ʹ end of one strand faces the 5ʹ end of the other strand. Sugar, phosphate, and nitrogenous bases contribute to the DNA structure. lego star wars cloud city walkthrough https://andygilmorephotos.com
