Transfer RNA molecule. Computer artwork of the double helix of tRNA (transfer ribonucleic acid), formed by spiralling paired strands of sugar phosphates, linked by nucleotide base pairs. Transfer RNA carries amino acid groups to ribosomes for protein synthesis. Protein synthesis is controlled by DNA (deoxyribonucleic acid, not seen) in the nucleus of a cell.
