THIN-LAYER chromatography on cellulose layers has been shown to be an effective method for separation and quantitative determination of nucleic acid bases, nucleosides and nucleotides 1–5 which ...

Nucleic acids are complex biological molecules that store and transmit genetic information ... In DNA, two complementary strands of nucleotides pair up through hydrogen bonds between the bases (A with ...

Hidden within the genetic code lies the "triplet code," a series of three nucleotides that determine a single amino acid. How did scientists discover and unlock this amino acid code? Once the ...

In the late nineteenth century, a German biochemist found the nucleic acids, long-chain polymers of nucleotides, were made up of sugar, phosphoric acid, and several nitrogen-containing bases.

Nucleic Acids These polymers appear to carry the pattern of living matter from one generation to the next. Their basic chain consists of sugars joined by phosphates.
