DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

Co-polymerization of glycol nucleic acid monomers with dicarboxylic acids in simulated early Earth drying environments readily gives rise to plausible prebiotic xeno nucleic acid co-polymers ...

Nucleic acids are made of biopolymers, which are naturally-occurring, repeated sets of monomers (making polymers) that then create nucleotides, which form nucleic acids.

Nucleic acids are made from just five different monomers, known as nucleotides; proteins are typically made from 20 different varieties of amino acid.

DNA stands for deoxyribonucleic acid. Nucleic acids are named for where they're found—inside the nuclei of cells—and for the acidic phosphate groups discovered in solution wherever DNA is present.
