The RNA world is a hypothetical stage in the evolutionary history of life on Earth in which self-replicating RNA molecules proliferated before the evolution of DNA and proteins. [1] The term also refers to the hypothesis that posits the existence of this stage. Alexander Rich first proposed the concept of the RNA world in 1962, [2] and Walter ...
Leslie Orgel was born in London, England, on 12 January 1927. He received his Bachelor of Arts degree in chemistry with first-class honours from the University of Oxford in 1948. In 1951 he was elected a Fellow of Magdalen College, Oxford and in 1953 was awarded his PhD in chemistry. Orgel started his career as a theoretical inorganic chemist ...
The RNA world hypothesis describes an early Earth with self-replicating and catalytic RNA but no DNA or proteins. [172] Many researchers concur that an RNA world must have preceded the DNA-based life that now dominates. [173] However, RNA-based life may not have been the first to exist.
Carl Richard Woese (/ ˈwoʊz /; [3] July 15, 1928 – December 30, 2012) was an American microbiologist and biophysicist. Woese is famous for defining the Archaea (a new domain of life) in 1977 through a pioneering phylogenetic taxonomy of 16S ribosomal RNA, a technique that has revolutionized microbiology. [4][5][6][7] He also originated the ...
The Major Transitions in Evolution. The Major Transitions in Evolution is a book written by John Maynard Smith and Eörs Szathmáry (Oxford University Press, 1995). [1][2][3][4] Maynard Smith and Szathmary authored a review article in Nature. [5] Transitions described in the book. Transition from:
RNA can also act as a hereditary molecule, which encouraged Walter Gilbert to propose that in the distant past, the cell used RNA as both the genetic material and the structural and catalytic molecule rather than dividing these functions between DNA and protein as they are today; this hypothesis is known as the "RNA world hypothesis" of the ...
He is best known for his work on the origin of life, having written two books on the topic: Origins, a Skeptic’s Guide to the Creation of Life on Earth (1986) and Planetary Dreams (1999). He opposed the RNA world hypothesis, and held that the spontaneous emergence of a molecule as complicated as RNA is highly unlikely. Instead, he proposed ...
RNP world. The RNP world is a hypothesized intermediate period in the origin of life characterized by the existence of ribonucleoproteins. [1] The period followed the hypothesized RNA world and ended with the formation of DNA and contemporary proteins. [2] In the RNP world, RNA molecules began to synthesize peptides.
