The RNA world hypothesis, if true, has important implications for the definition of life and the origin of life. For most of the time that followed Franklin , Watson and Crick 's elucidation of DNA structure in 1953, life was largely defined in terms of DNA and proteins: DNA and proteins seemed the dominant macromolecules in the living cell ...
The Let-7 microRNA precursor gives rise to let-7, a microRNA (miRNA) involved in control of stem-cell division and differentiation. [1] let-7, short for "lethal-7", was discovered along with the miRNA lin-4 in a study of developmental timing in C. elegans, [2] making these miRNAs the first ever discovered.
Molecular Biology of the Cell is a cellular and molecular biology textbook published by W.W. Norton & Co and currently authored by Bruce Alberts, Rebecca Heald, David Morgan, Martin Raff, Keith Roberts, and Peter Walter. The book was first published in 1983 by Garland Science and is now in its seventh edition.
Molecular biology / m ə ˈ l ɛ k j ʊ l ər / is a branch of biology that seeks to understand the molecular basis of biological activity in and between cells, including biomolecular synthesis, modification, mechanisms, and interactions. [1] [2] [3]
Molecular biology is the study of molecular underpinnings of the biological phenomena, focusing on molecular synthesis, modification, mechanisms and interactions. The central dogma of molecular biology , where genetic material is transcribed into RNA and then translated into protein , despite being oversimplified, still provides a good starting ...
Benjamin Lewin is a molecular biologist who founded the journal Cell [1] and authored the textbook Genes. [2] He is credited with building Cell into a recognized journal of cellular biology in a short period of time to rival Nature and Science. [3] Following a tutorial session at the University of Sussex, Lewin became editor of Nature New Biology.
Fundamentals of Biochemistry: Life at the Molecular Level is a biochemistry textbook written by Donald Voet, Judith G. Voet and Charlotte W. Pratt. [1] [2] Published by John Wiley & Sons, it is a common undergraduate biochemistry textbook. As of 2016, the book has been published in 5 editions. [3]
The discovery of DNA as the blueprint for life and breakthroughs in molecular genetics research came from the combined works of many scientists. In 1869, chemist Johann Friedrich Miescher, who was researching the composition of white blood cells, discovered and isolated a new molecule that he named nuclein from the cell nucleus, which would ultimately be the first discovery of the molecule DNA ...
