Some articles on nucleotides:

Toscana Virus - Virology - Structure and Genome
... L is about 6,400 nucleotides in length, M about 4,200 nucleotides in length, and S about 1,900 nucleotides in length ...
Recombination Signal Sequences
... RSSs are composed of seven conserved nucleotides (a heptamer) that reside next to the gene encoding sequence followed by a spacer (containing either 12 or 23 ... one with a spacer of 12 nucleotides will be recombined with one that has a spacer containing 23 nucleotides) ...
Nucleotide Salvage
... A salvage pathway is a pathway in which nucleotides (purine and pyrimidine) are synthesized from intermediates in the degradative pathway for nucleotides ... and nucleosides can then be converted back into nucleotides ...
Artificial Gene Synthesis - Standard Methods - Chemical Synthesis of Oligonucleotides
... Oligonucleotides are chemically synthesized using nucleotides, called phosphoramidites, normal nucleotides which have protection groups preventing amine, hydroxyl groups and ... this process is only practical for producing short sequences of nucleotides ...
