Nucleotides and Nucleic Acids

Key Principles Nucleic acids are both repositories and functional expression of biological information. The transmission of biological information relies on molecular complementarity. Nucleoside triphosphates occupy a central role in cellular metabolism, serving as an energy currency and as important regulatory signals

1. Some basic definitions and conventions Nucleotides

Different Classes of Nucleic Acids The two major classes of nucleic acids are DNA and RNA. DNA has only one biological role: store information. The information to make all the functional macromolecules of the cell is preserved in DNA. RNA has a number of important biological functions. Its central one is transferring information from DNA to protein
