Identical DNA codes discovered in different plant species - 2 views

  • found identical sequences of DNA located at completely different places on multiple plant genomes
  • Although the scientists found identical sequences between plant species, just as they did between animals, they suggested the sequences evolved differently.
  • find identical sequences in plant DNAs
  • ...9 more annotations...
  • identical sections weren't found at the same points
  • genomes of six animals (dog, chicken, human, mouse, macaque and rat)
  • six plant species (Arabidopsis, soybean, rice, cottonwood, sorghum and grape)
  • found long strings of identical code in different species of animals' DNA
  • expect to see convergent evolution, but we don't
  • Plants and animals are both complex multi-cellular organisms that have to deal with many of the same environmental conditions, like taking in air and water and dealing with weather variations, but their genomes code for solutions to these challenges in different ways
  • could help in the development of new medicines
  • used to find identical sequential patterns in an organism's entire set of proteins
  • lead to finding new targets for existing drugs or studying these drugs' side effects
  •  
    A computer algorithm found identical sequences of DNA in different places of various plant species' genomes. The same has been found in animals. This could prove to be beneficial in the development of new medicines (for testing drug side effects).

EBSCOhost: What Makes Each Brain Unique - 0 views

    NEUROSCIENCE How can identical twins grow up with different personalities? "Jumping genes" move around in neurons and alter the way they work YOUR BRAIN IS SPECIAL. So is mine. Differences arise at every level of the organ's astonishingly intricate architecture; the human brain contains 100 billion neurons, which come in thousands of types and collectively form an estimate of more than 100 trillion interconnections.
