discovered why we look the same as other people in our family.It is because of small things called "genes"(基因) in our body.In 1953,two scientists,Watson and Crick,found out that those small parts are really messages.They're written in the DNA with a special language.In 1961,another ...

Understanding DNA: Five key scientists who unravelled the helix Who really discovered DNA? DNA research was to benefit from the post-WWII mood in science, as many physicists who had been employed in war work turned their attention to the more benign biological problems. Among them was Maurice ...
Researchers who confine their search for our higher powers to some yet- to-be-discovered genie-like faculties of the cortex, while ignoring both our unique Needs and Faculties, and the remarkable functions of the Reticular Activating System, (or ERTAS, the extended reticular-thalamic system ―whic...
This day celebrates the day when James Watson, Francis Crick, Maurice Wilkins, Rosalind Franklin, and their colleagues published papers in a journal called Nature on how DNA is structured- in 1953, also known as the day when the double helix structure of DNA was discovered. Another well-timed...
Despite this, new chemical insights continue to be uncovered, including recent findings that may explain newly discovered functions for many DNA polymerases in DNA repair and mutation. Some of these reactions involve non-Watson–Crick base-pairing. In addition, certain DNA polymerases have been ...
That radiation can cause genetic mutation in living organisms was discovered by the US geneticistHermann Muller(1890–1967). In 1927 he published a paper inScience(6684)entitled “Artificial Transmutation of the Gene”, his title ambitiously and audaciously invoking the artificial transmutation of eleme...
Peloubet, a partner in a New York accounting firm. He wrote about the use of accounting in courtroom proceedings as part of testimony, but acknowledged that investigation was becoming more prevalent for accountants due to the increase in government agencies that regulated financial practices. ...
