Listening to the whispers of individual cells

For the cells in our bodies to function as a unit, they must communicate with one another constantly. They secrete signalling molecules—ions, proteins and nucleic acids—that are picked up by adjacent cells, which in turn ...

Biologists design a plug-and-play controller for gene expression

Researchers from two University of Texas System institutions have engineered biological components that can rewire genetic response pathways, creating a template for designing new cellular behaviors with wide-ranging potential ...

A rapid, easy-to-use DNA amplification method at 37 Celcius

Scientists in Japan have developed a way of amplifying DNA on a scale suitable for use in the emerging fields of DNA-based computing and molecular robotics. By enabling highly sensitive nucleic acid detection, their method ...

Study uncovers key step in cell protein production

Scientists at the University of Sheffield have discovered how genes create proteins in research which could aid the development of treatments for human diseases.

New nanomedicine slips through the cracks

In a recent study in mice, researchers found a way to deliver specific drugs to parts of the body that are exceptionally difficult to access. Their Y-shaped block catiomer (YBC) binds with certain therapeutic materials forming ...

Nucleic acid

A nucleic acid is a macromolecule composed of chains of monomeric nucleotides. In biochemistry these molecules carry genetic information or form structures within cells. The most common nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Nucleic acids are universal in living things, as they are found in all cells and viruses. Nucleic acids were first discovered by Friedrich Miescher in 1871.

Artificial nucleic acids include peptide nucleic acid (PNA), Morpholino and locked nucleic acid (LNA), as well as glycol nucleic acid (GNA) and threose nucleic acid (TNA). Each of these is distinguished from naturally-occurring DNA or RNA by changes to the backbone of the molecule.
