Biochemistry is the study of chemical processes within and relating to living organisms. Molecular biology is the branch of biology that seeks to understand the molecular basis of biological activity in and between cells, including molecular synthesis, modification, mechanisms, and interactions.
I was very good at working with people that weren’t actors. In 2003, when we were making ‘Elephant,’ I thought we really needed to use real high school kids rather than kids that were ...
Four decades ago, a rare earth processing plant on France's Atlantic coast was one of the largest in the world, churning out materials used to make colour televisions, arc lights and camera lenses.
A rare exception to the dominance of α-amino acids in biology is the β-amino acid beta alanine (3-aminopropanoic acid), which is used in plants and microorganisms in the synthesis of pantothenic acid (vitamin B 5), a component of coenzyme A. In mammalian nutrition
The highest natural ground surface temperature ever recorded may have been an alleged reading of 93.9 °C (201.0 °F) at Furnace Creek, California, United States, on 15 July 1972. [7] In 2011, a ground temperature of 84 °C (183.2 °F) was recorded in Port Sudan, Sudan. [8] The theoretical maximum possible ground surface temperature has been ...
RNA world. A comparison of RNA ( left) with DNA ( right ), showing the helices and nucleobases each employs. 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 ...
