Networking in plain English. Cisco IP Classless Command. When Cisco routers have to forward packets, they will check their routing table and they use longest prefix matching to find the best match. If you donât have a best match then the router will use a default route (if you have one). Otherwise, the packet will be dropped.
Franklinâs images allowed James Watson and Francis Crick to create their famous two-strand, or double-helix, model. At Kingâs College London, Rosalind Franklin obtained images of DNA using X-ray crystallography, an idea first broached by Maurice Wilkins.
In the early 1950s two scientists, Rosalind Franklin and Maurice Wilkins, studied DNA using x-rays. Franklin produced an x-ray photograph that allowed two other researchers, James Watson and Francis Crick to work out the 3D structure of DNA. The structure of DNA was found to be a double helix. In 1962 Crick and Watson, along with Wilkins, received the Nobel Prize in Physiology or Medicine for their discovery. Rosalind Franklin had died four years earlier and her pivotal contribution wasn't acknowledged until much later. DNA double helix. Page: 1  1. 2  2. 3  3. 4  4.
