In a groundbreaking discovery, scientists have identified all five nucleobases responsible for storing information in DNA and RNA in meteorites that fell to Earth within the last century. These nucleobases - adenine, guanine, cytosine, thymine, and uracil - are the fundamental building blocks of the genetic code for all life on Earth. The findings, published in Nature … [Read more...] about Meteorites Unearth All DNA and RNA Bases, Suggesting Extraterrestrial Origin
