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?

A nucleic acid is a long molecule made up of smaller molecules called nucleotides. Nucleic acids were discovered in 1868, when twenty-four-year-old Swiss physician Friedrich Miescher isolated a ...

Fully assembled, the sequence of base pairs is a compound molecule called a nucleic acid. Living organisms are constantly building new cells or repairing old ones. To do this they have to make ...

that the DNA molecule exists in the form of a three-dimensional double helix. More than 50 years passed before the significance of Miescher's discovery of nucleic acids was widely appreciated by ...

As early as 1943 Oswald Avery proved what had been suspected: that DNA, a nucleic acid ... as their main tool -- beaming X-rays through the molecule yielded a shadow picture of the molecule's ...

The resulting RNA molecule, typically mRNA, carries the genetic message from the nucleus to the cytoplasm for protein synthesis. Nucleic acids are the foundation of genetic engineering techniques, ...

By moving the trapped bead relative to a fixed surface, forces can be applied to the tethered molecule. Optical tweezers offer high force and spatial resolution, making them suitable for studying the ...
