(a)
Interpretation:
The name of each compound shown in the ball-and-stick model should be determined.
Concept Introduction:
In the ball-and-stick model, each atom has a specific color.
Red − Oxygen atoms.
White − H atoms.
Black − Carbon atoms.
Blue − N atoms.
(b)
Interpretation:
The compound needs to be classified as a base, nucleoside or
Concept Introduction:
In the
From the parent compound pyrimidine, there are three bases derived namely cytosine, uracil, and thymine.
There are two bases with two rings are derived from the parent compound purine which is adenine and guanine.
The anomeric carbon of monosaccharide joined with a nitrogen atom to form a nucleoside.
To make a nucleotide; a phosphate group is added to the 5'-OH of a nucleoside.
Nucleotides are named by adding the term 5'-monophosphate to the name of the nucleoside from whichthey are derived.
Ribonucleotides are derived from ribose. Deoxyribonucleotides arederived from 2-deoxyribose.
(c)
Interpretation:
Whether the compound is a component of RNA, DNA or both should be determined.
Concept Introduction:
There are two types of nucleotides. They are DNA and RNA. Nucleic acids are composed of monomers called nucleotides.
There are five common nitrogen-containing bases that are present in nucleic acids; cytosine, uracil, thymine, adenine, and guanine.
