MicroRNA (miRNA) precursor,molecular model.This miRNA (micro ribonucleic acid) precursor will be further processed into an even shorter mature miRNA oligonucleotide that can regulate the expression of a target gene.The precursor shown here is the human miR-17 stem-loop (hsa-mir-17),which is believed to play a role in several types of breast cancer
SPL024273
Sibutramine anti-obesity drug,molecular model.This drug was withdrawn from the market in 2010 due to safety concerns.Atoms are represented as spheres and are colour-coded: hydrogen (white),carbon (grey),nitrogen (blue),chlorine (green)

Domperidone anti-sickness drug,molecular model.Atoms are represented as spheres and are colour-coded: hydrogen (white),carbon (grey),oxygen (red),nitrogen (blue) and chlorine (green)
SPL024261
DNA nucleosome,molecular model.This is the fundamental repeating unit used to package DNA (deoxyribonucleic acid) inside cell nuclei.DNA's double helix structure (red) is seen here tightly coiled round a core of histone proteins (green)
SPL024277
Transfer RNA (tRNA),molecular model.tRNA (transfer ribonucleic acid) translates messenger RNA (mRNA) into a protein product.Each tRNA molecule carries a specific amino acid,in this case tryptophan
SPL024281
Penicillin G,molecular model.Beta-lactam antibiotic used in the treatment of bacterial infections.Atoms are represented as spheres and are colour-coded: hydrogen (white),carbon (grey),oxygen (red),nitrogen (blue) and sulphur (yellow)
SPL024295
Transfer RNA-synthetase complex molecule.Molecular model of a human tryptophanyl-tRNA synthetase molecule (red) complexed with a tRNA(Trp) molecule (blue).tRNA (transfer ribonucleic acid) translates messenger RNA (mRNA) into a protein product.Each tRNA molecule carries a specific amino acid,in this case tryptophan.Tryptophan is attached to tRNA(Trp) by the enzyme tryptophanyl-tRNA synthetase
