Direct sequencing means that the letters of the genetic code are read directly, as if with a magnifying glass. A DNA or RNA strand has a diameter of only two nanometers, so the magnification must ...

They have successfully analyzed DNA’s closest relative, RNA. Direct sequencing means that the letters of the genetic code are read directly, as if with a magnifying glass.

Posted: May 19, 2009: Quantum dots light up individual DNA binding proteins (Nanowerk Spotlight) Proteins that bind to specific sites of DNA are essential to all biological functions of DNA.These ...

For a long time, scientists depended on luck to find new proteins. In 1840, for example, Friedrich Ludwig Hünefeld, a German ...

Not all DNA looks like the familiar twisted ladder. Sometimes, parts of our genetic code fold into unusual shapes. One such structure, the G-quadruplex (G4), looks like a knot.

Bacteria and other single-celled organisms have been using the combination of guide RNA and a scissors-like protein to chop up the DNA of unfriendly viruses for hundreds of million of years.

The DNA codons are identical to the RNA codons, except for the one base thymine (T), which replaces uracil (U) in the RNA codons. The DNA codons and the amino acids they represent are tabulated below: ...
