What is nucleic acid?

  • (noun): (biochemistry) any of various macromolecules composed of nucleotid chains that are vital constituents of all living cells.

Nucleic Acid

Nucleic acids are large biological molecules essential for all known forms of life. They include DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). Together with proteins, nucleic acids are the most important biological macromolecules; each is found in abundance in all living things, where they function in encoding, transmitting and expressing genetic information.

Spin Column-based Nucleic Acid Purification
... Column-based nucleic acid purification is a solid phase extraction method to quickly purify nucleic acids ... This method relies on the fact that the nucleic acid may bind (adsorption) to the solid phase (silica or other) depending on the pH and the salt content of the buffer, which ... Therefore, three stages are The sample is added to the column and the nucleic acid binds due to the lower pH (relative to the silanol groups on the column) and ...
Adaptor Hypothesis
