Tom Blundell — crystal structures of HIV protease, renin, insulin and other hormones, growth factors, receptors, and proteins important in cell signalling and DNA repair; developed structure-guided and fragment-based approaches to drug design; Jagadish Chandra Bose (Indian, 1858–1937) [1] Detlev Wulf Bronk (American, 1897–1975) [1]
The DNA double helix structure proposed by Watson and Crick was based upon "Watson-Crick" bonds between the four bases most frequently found in DNA (A, C, T, G) and RNA (A, C, U, G). However, later research showed that triple-stranded, quadruple-stranded and other more complex DNA molecular structures required Hoogsteen base pairing.
In 1953, with the help of Maurice Wilkins and Rosalind Franklin's X-ray crystallography, James Watson and Francis Crick proposed DNA is structured as a double helix. [1] In the 1960s, one main DNA mystery scientists needed to figure out was the number of bases found in each code word, or codon, during transcription.

He characterized the different forms of nucleic acid, DNA from RNA, and found that DNA contained adenine, guanine, thymine, cytosine, deoxyribose, and a phosphate group. [ 1 ] He was born into a Litvak (Lithuanian Jewish) family as Fishel Rostropovich Levin in the town of Žagarė in Lithuania , then part of the Russian Empire , but grew up in ...
After that, E. coli cells with only 15 N in their DNA were transferred to a 14 N medium and were allowed to divide; the progress of cell division was monitored by microscopic cell counts and by colony assay. DNA was extracted periodically and was compared to pure 14 N DNA and 15 N DNA. After one replication, the DNA was found to have ...
Scientists potentially uncovered a glueball particle, an enigmatic entity believed to be made entirely of the strong nuclear force's gluons. Scientists May Have Found a Particle Made of Pure Force ...
