“Such a setting would be very common on volcanic islands on early Earth which offered the necessary dry conditions for RNA ...

However, in the half-century since the structure of DNA was first elaborated, scientists have learned that RNA does much more than simply play a role in protein synthesis. For example, many types ...

Deep within the nucleus of every cell lies a structure smaller than a pinpoint that may hold the secret to aging. Scientists ...

This evolutionary conservation highlights the fundamental role of tRNA in the essential process of protein synthesis. The basic structure and function of tRNAs have remained largely unchanged over ...

which catalyzes the formation of peptide bonds between amino acids during protein synthesis. This discovery led to the concept of the ribosome as a ribozyme, an RNA molecule with enzymatic properties.

A study published in PNAS reveals how a bacterial pathogen coordinates N-acetylneuraminic acid (Neu5Ac) metabolism at the post-transcriptional level via a novel small noncoding RNA to promote ...

This process of protein synthesis occurs in two stages - transcription and translation. When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA).
