While codons (combinations of three nucleotides) may vary in which do what functions, a long-standing rule was that each codon serves one specific purpose. New evidence, however suggests that ...

It is well known that codon bias and gene expression are correlated. The established explanation is that mRNAs with a high codon adaptation index (CAI) — that is, with a high number of 'preferred' ...

Everything on Earth is made of atoms, most of which are closely packed together in the form of minerals. Life has its uses for minerals—ask a coral reef—but its essence lies in atoms arranged as ...
