Dictionary » N » Nucleoside NucleosideDefinition noun, plural: nucleosides (1) A nitrogenous base (purine or pyrimidine) bound to a pentose sugar ribose or deoxyribose. (2) A glycoside formed from the hydrolysis of nucleic acid.
A phosphate group attached to a nucleoside would make a nucleotide. Depending on the pentose sugar component, a nucleoside may be a ribonucleoside (e.g. adenosine, guanosine, cytidine, and uridine) or a deoxyribonucleoside (e.g. deoxyadenosine, deoxyguanosine, deoxycytidine, deoxythymidine).
Related terms: nucleoside analogue, nucleoside diphosphate. Compare: nucleotide.

Results from our forumRe: Nucleoside analogs and ionizing radiation... some info on radiation therapy: http://www.cancer.gov/cancertopics/factsheet/Therapy/radiation I should think the same principle would apply with nucleoside analogs. They apply the treatment only to the tumor cells, selectively stopping them from dividing by disrupting DNA replication only in ...

Re: What is the difference between chromatide and nucleotide?The nucleotide is the single unit of DNA comprising the sugar molecule (deoxyribose) which is bonded to the base (A/T/C/G) (this combo is the nucleoside),plus the phosphate group (which bonds the C3 carbon atom of one sugar molecule to the C5 carbon molecule of the next one along in a phospodiester ...

Re: Crosswords will be the death of me..... but unless you're supposed to use the acronym that would be a rather long entry spelled-out. I suppose "nucleotide kinase" or "nucleoside kinase" are possibilities, though again, these are a bit longish for cross word puzzles.
