RNA

Asteroid Ryugu: All five canonical bases of DNA and RNA were identified in samples returned from it by the Hayabusa2 spacecraft, a finding that strengthens the hypothesis that carbonaceous asteroids contributed to the starting materials for life on Earth.

All five bases of DNA and RNA were found in the asteroid Ryugu

  • One response
New research on Ryugu samples, combined with findings from the asteroid Bennu, from which the samples were brought to Earth, strengthens the hypothesis that carbonaceous asteroids provided the early Earth with important starting materials for the chemistry of life.

  • One response
Toxic proteins accumulate in the brains of Alzheimer's patients. In the familial Alzheimer's patients, the accumulation mechanism is clear since there is a circumstantial relationship between the mutations and the identity of the defective proteins. In the random disease, on the other hand, the cause of the accumulation of proteins
