Purine Nucleosides. Nucleosides, Purine . Purines with a RIBOSE attached that can be phosphorylated to PURINE NUCLEOTIDES. . 0.77
Nucleic Acids, Nucleotides, and Nucleosides. Complex compounds of high molecular weight occurring in living cells. These are basically of two types, ribonucleic (RNA) and deoxyribonucleic (DNA) acids, both of which consist of nucleotides (nucleoside phosphates linked together by phosphate bridges). . 0.77
Nucleosomes. Dinucleosomes . Polynucleosomes . Dinucleosome . Nucleosome . Polynucleosome . The repeating structural units of chromatin, each consisting of approximately 200 base pairs of DNA wound around a protein core. This core is composed of the histones H2A, H2B, H3, and H4. . 0.73
Nucleotides. The monomeric units from which DNA or RNA polymers are constructed. They consist of a purine or pyrimidine base, a pentose sugar, and a phosphate group. (From King & Stansfield, A Dictionary of Genetics, 4th ed) . 0.73
Nucleons. Nucleon . Subatomic particles that are either protons or neutrons. . 0.70
Nucleoside Q. Nucleoside Q* . Q Nucleoside . Q-Ribonucleoside . Queuosine . Q Ribonucleoside . A modified nucleoside which is present in the first position of the anticodon of tRNA-tyrosine, tRNA-histidine, tRNA-asparagine and tRNA-aspartic acid of many organisms. It is believed to play a role in the regulatory function of tRNA. Nucleoside Q can be further modified to nucleoside Q*, which has a mannose or galactose moiety linked to position 4 of its cyclopentenediol moiety. . 0.70
