“Avery had described one of the most momentous discoveries in the history of science, and no one could think of anything to say.” — Matthew Cobb Copy Share Image
“the transforming principle could not be made of DNA because nucleic acids were all alike. As” — Matthew Cobb Copy Share Image
“DNA composition was constant in all tissues of a given species, but each species had its own profile.” — Matthew Cobb Copy Share Image
“The genetic code is a product of biology and is messy, illogical and inelegant. It is highly redundant, but to bewilderingly varied degrees: one… — Matthew Cobb Copy Share Image
“Wiener and Rosenblueth showed that purposeful, goal-directed behaviour can be seen in organisms and machines, and that it operates through what is known as… — Matthew Cobb Copy Share Image
“As Jacob put it in 1977, natural selection does not design, it tinkers with what is available.” — Matthew Cobb Copy Share Image
“Genes were no longer mysterious embodiments of specificity, they were information – a code – that could be transmitted (another word from the electronic… — Matthew Cobb Copy Share Image
“In fact they are historical, carrying the baggage of their evolutionary past, and have not been designed at all. They are often far from… — Matthew Cobb Copy Share Image
“In the discussion, Gulland was asked about the possibility that a DNA molecule might be a helix, held together by the presence of evenly… — Matthew Cobb Copy Share Image
“By the end of the 1940s, support for the hypothesis that DNA had a fundamental role in heredity had grown much stronger.” — Matthew Cobb Copy Share Image
“In typically generous fashion, Crick was offering Nirenberg the opportunity to step into history as the man who had cracked the genetic code.” — Matthew Cobb Copy Share Image
“Every result converged on the same conclusion: the transforming principle was composed of DNA. The discussion section of the article outlined the genetic context… — Matthew Cobb Copy Share Image
“Avery had described one of the most momentous discoveries in the history of science, and no one could think of anything to say.” — Matthew Cobb Copy Share Image
“By the end of the 1940s, it was widely known that the levels of protein in the transforming principle were effectively zero.” — Matthew Cobb Copy Share Image
“If the adaptor hypothesis were true (and it was), this meant that the role of DNA and RNA would be reduced to simply carrying… — Matthew Cobb Copy Share Image
“Part of the problem was that no one knew exactly how a cell took a nucleic acid sequence and turned it into a blob… — Matthew Cobb Copy Share Image
