Nitrogenous Bases
Cards in this deck (16)
- 1A nucleotide contains_.Nitrogenous base, 5 carbon sugar, phosphate group
- 2Nitrogenous base structureRing structure containing carbon and nitrogen atoms
- 3PurinesType of nitrogenous base structure with double rings (ex. guanine and adenine)
- 4PyrimidinesNitrogenous base structure consisting of a single ring (ex. cytosine, uracil, thymine)
- 55-carbon sugar differs by _.Presence of OH group on 2' carbon
- 6The difference between deoxyribose and ribose is _.Deoxyribose has one less oxygen atom at the 2' position than ribose
- 7NucleosideNitrogenous base and pentose sugar (no phosphate group)
- 8RibonucleosidesRibose is the sugar, bound to whichever nitrogenous base (Ex. adenosine, ctyidine, guanosine, uridine)
- 9DeoxyribonucleosidesDeoxyribose is the sugar, uses ribonucleoside names and adds "deoxy" prefix for DNA (Ex. Deoxyadenosine, deoxycytidine, deoxyguanosine, deoxythymidine)
- 10Naming nucleotidesTake nucleoside name and add number of phosphate groups attached (Ex. Adenosine triphosphate: ribose bonded to adenine with 3 phosphate groups on the 5')
- 11Nucleoside monophosphateNucleotides with a single phosphate group (NMP)
- 12Nucleoside diphosphateNucleoside and 2 phosphates (NDP)
- 13Nucleoside TriphosphateNucleoside and 3 phosphates (NTP)
- 143',5' phosphodiester bondPhosphate on the 5' end of the sugar on one nucleotide attaches to 3' carbon on the sugar of another nucleotide
- 15Linkage of nucleotides via phosphodiester bonds forms _.Sugar-phosphate backbone of DNA
- 16DirectionalityDistinct chemical ends, top of strand has different chemical group than at the bottom, based on orientation of the sugar molecules within the strand
