Tips To Grow Tomatoes With Natural Farming - 0 views

  •  
    Growing tomatoes in pots is very interesting in terms of health benefits. Before you plant a tomato plant, fill the pot with soil and mix with small amount fertilizer thereafter finish off with adding composite over the soil to help root development.

RNA world easier to make : Nature News - 0 views

  • John Sutherland and his colleagues from the University of Manchester, UK
  • ribonucleotide
  • building block of RNA
  • ...29 more annotations...
  • Donna Blackmond, a chemist at Imperial College London.
  • strong evidence for the RNA world
  • 'RNA world' hypothesis, which suggests that life began when RNA, a polymer related to DNA that can duplicate itself and catalyse reactions
  • chemists had thought the subunits would probably assemble themselves first, then join to form a ribonucleotide
  • three distinct parts: a ribose sugar, a phosphate group and a base
  • RNA polymer is a string of ribonucleotides
  • efforts to connect ribose and base together have met with frustrating failure
  • researchers have now managed to synthesise
  • ribonucleotides
  • remedy is to avoid producing separate ribose-sugar and base subunits
  • makes a molecule whose scaffolding contains a bond that will
  • be the key ribose-base connection
  • atoms are then added around this skeleton
  • final connection is to add a phosphate group
  • influences the entire synthesis
  • acting as a catalyst, it guides small organic molecules into making the right connections
  • What we have ended up with is molecular choreography
  • objectors to the RNA-world theory say the RNA molecule as a whole is too complex to be created using early-Earth geochemistry
  • flaw is in the logic — that this experimental control by researchers in a modern laboratory could have been available on the early Earth
  • Robert Shapiro, a chemist at New York University
  • early-Earth scenarios
  • heating molecules in water, evaporating them and irradiating them with ultraviolet light
  • results showing that they can string nucleotides together
  • ultimate goal is to get a living system (RNA) emerging from a one-pot experiment
  • need to know what the constraints on the conditions are first
  • Shapiro sides with
  • another theory of life's origins
  • because RNA is too complex to emerge from small molecules, simpler metabolic processes
  • eventually catalysed the formation of RNA and DNA
