Nucleic acids are complex biological molecules that store and transmit genetic information in all living organisms. They are essential for the survival and reproduction of life on Earth. The two main ...

The DNA double helix is composed of two DNA molecules whose sequences are complementary to each other. The stability of the duplex can be fine-tuned in the lab by controlling the amount and location ...

RNA could be considered DNA’s younger sibling. From the very beginning, RNA’s milestones came later and attracted less attention than DNA’s milestones. For example, the discovery of DNA’s structure ...

Long known as a messenger within cells, RNA is increasingly seen as life’s molecular communication system — even between organisms widely separated by evolution. For a molecule of RNA, the world is a ...

Chemists at UCL and the MRC Laboratory of Molecular Biology have demonstrated how RNA (ribonucleic acid) might have replicated itself on early Earth – a key process in the origin of life. Scientists ...
