(a)
Expert Solution
Interpretation Introduction
Interpretation: The validation of the given statement concerning nucleic acids has to be predicted.
Concept introduction: Nucleic acids are the polymers of nucleotides. Nucleic acids are of two types- deoxyribonucleic acid and ribonucleic acid. Deoxyribonucleic acid transfers the genetic information and ribonucleic acids synthesize proteins.
Answer to Problem 22.1EP
The given statement that “All cells in higher organisms contain both DNA and RNA” is true.
Explanation of Solution
Proteins are the building blocks in higher organisms. RNA is necessary for the synthesis of proteins and DNA stores the genetic information. Therefore, all cells in higher organisms contain both DNA and RNA.

Answer to Problem 22.1EP
The statement that, “Structurally, DNA but not RNA, is an unbranched polymer” is false.
Explanation of Solution
DNA and RNA, both are similar in structure. DNA and RNA are the polymers of nucleotides. A nucleotide consists of a phosphate group, a sugar and a base. This structure gives the DNA and RNA molecule a branched shape. Therefore, DNA and RNA both are unbranched polymers.

Answer to Problem 22.1EP
The statement that, “Involvement with protein synthesis is the primary function for RNA” is true.
Explanation of Solution
RNA is a polymer of nucleotide. The major function of RNA is the synthesis of protein.

Expert Solution
Interpretation Introduction
Interpretation: The validation of the given statement concerning nucleic acids has to be predicted.
Concept introduction: Nucleic acids are the polymers of nucleotides. Nucleic acids are of two types- deoxyribonucleic acid and ribonucleic acid. Deoxyribonucleic acid transfers the genetic information and ribonucleic acids synthesize proteins.
Answer to Problem 22.1EP
The statement that, “DNA is found primarily in a cell’s nucleus.” is true.
Explanation of Solution
DNA is a polymer of nucleic acid. DNA transfers the genetic information. DNA is located in the nucleus of a cell.
