On Thymus Nucleic Acid

A consideration of the earlier investigations of the nucleic acids would lead us to the conclusion that these substances yield among their hydrolytic products four purin derivatives, namely, xanthin, hypoxanthin, guanin, and adenin. Of these four bases hypoxanthin was the first discovered in this connection and was for a long time looked upon as the most constant in its occurrence, and, therefo...

The Nucleic Acid Database: A resource for nucleic acid science.

The Nucleic Acid Database (NDB) distributes information about nucleic acid-containing structures. Here the information content of the database as well as the query capabilities are described. A summary of how the technology developed by this project has been used to develop other macromolecular databases is given.

Studies on Nucleic Acid Metachromasy

Acrolein-fixed, polyester wax-embedded tissue sections showed excellent preservation of light microscopic architecture and, when stained with toluidine blue, intense color contrast between DNA, which stained orthochromatically, and RNA, which stained metachromatically. This method has practical value for differentiating DNA from RNA in the same section. The color contrast was impaired by substi...

Molecular Beacons of Xeno-Nucleic Acid for Detecting Nucleic Acid

Molecular beacons (MBs) of DNA and RNA have aroused increasing interest because they allow a continuous readout, excellent spatial and temporal resolution to observe in real time. This kind of dual-labeled oligonucleotide probes can differentiate between bound and unbound DNA/RNA in homogenous hybridization with a high signal-to-background ratio in living cells. This review briefly summarizes t...
