Concept explainers
Label each statement as pertaining to DNA, RNA, or both.
- The polynucleotide is double stranded.
- The polynucleotide may contain adenine.
- The polynucleotide may contain dGMP.
- The polynucleotide is a
polymer of ribonucleotides.

(a)
Interpretation:
Whether the statement "the polynucleotide is double stranded" pertaining to DNA, RNA or both should be determined.
Concept Introduction:
There are two types of nucleotide. They are DNA and RNA. Nucleic acids are composed of monomers called nucleotides.
Answer to Problem 22.27P
DNA
Explanation of Solution
DNA consists of two polynucleotide strands which wind into a right-handed double helix.
RNA is single stranded structure.

(b)
Interpretation:
Whether the statement "the polynucleotide may contain adenine" pertaining to DNA, RNA or both should be determined.
Concept Introduction:
There are two types of nucleotide. 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.
Answer to Problem 22.27P
Both DNA and RNA
Explanation of Solution
There are five common nitrogen-containing bases that are present in nucleic acids; cytosine, uracil, thymine, adenine and guanineDNA contains the bases A, G, C, and T.
RNA contains the bases A, G, C, and U.

(c)
Interpretation:
Whether the statement "the polynucleotide may contain dGMP" pertaining to DNA, RNA or both should be determined.
Concept Introduction:
dGMP stands for Deoxyguanosine 5'-monophosphate. Deoxyribonucleotides are derived from 2-deoxyribose.
Answer to Problem 22.27P
DNA
Explanation of Solution
dGMP stands for Deoxyguanosine 5'-monophosphate. Deoxyribonucleotides are derived from 2-deoxyribose.DNA is a polymer of deoxyribonucleotides.
Therefore, dGMP present in DNA.

(d)
Interpretation:
Whether the statement "the polynucleotide is a polymer of ribonucleotides" pertaining to DNA, RNA or both should be determined.
Concept Introduction:
To make a Nucleotides; 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.
Answer to Problem 22.27P
RNA
Explanation of Solution
Ribonucleotides are derived from ribose. Deoxyribonucleotides are derived from 2-deoxyribose. DNA is a polymer of deoxyribonucleotides.
RNA is a polymer of ribonucleotides.
