RNA, which is one of life's most crucial molecules dealing with the synthesis of proteins, could be common in the universe, according to a new experiment that shows how RNA could easily have formed on Earth 4.3 billion years ago.
RNA (short for ribonucleic acid) is a simpler cousin of DNA, which is the molecule that contains the genetic information for our cellular biology. RNA comes in a trio of guises. There is messenger RNA (mRNA) that is produced from DNA and contains the genetic instructions for forming proteins. Then there's ribosomal RNA (rRNA) that creates ribosomes vital for producing proteins, and finally transfer RNA (tRNA) that does the actual synthesizing of the proteins from mRNA.
