Concept explainers
Interpretation:
The structure of guanosine needs to be drawn, the carbon in the sugar needs to be numbered and it should be classified as a ribonucleoside or a deoxyribonucleoside.
Concept Introduction:
DNA and RNA are
A
Only the base and the sugar portion of a nucleotide is called a nucleoside.
Bases in DNA/RNA:
There are only five common nitrogen-containing bases are present in DNA/RNA, which are derived either from pyrimidine or purine.
Sugar in DNA/RNA:
The monosaccharide in RNA is D-ribose.
In DNA, the monosaccharide is D-2-deoxyribose (lacks a hydroxyl group at C2).
Naming Nucleosides:
The suffix − idine is used to name a nucleoside derived from a pyrimidine base.
The suffix -osine is used to name a nucleoside derived from a purine base.
The prefix deoxy- is used if hydroxyl group is missing at C-2 position of the sugar.
