Chapter 24, Problem 14STP

Interpretation Introduction

Interpretation: To state whether the given statement is true or false.

Concept Introduction: An unbranched polymer that is made up of nucleotides (monomeric units) is known as nucleic acid. The nucleotide is a combination of sugar, phosphate, and base.

The nucleic acids are categorized into two types that are as follows:

• Deoxyribonucleic acid (DNA)
• Ribonucleic acid (RNA)

Answer to Problem 14STP

Statement II is the correct explanation for statement I.

Explanation of Solution

The base pairing occurs in both DNA and RNA molecules. It is known that the pairing is done in a way that A is always paired with T, while G is paired with C.

In the portion of a DNA molecule, the sequence of bases is known as genes, these carry the information or codes that are required for the formation of proteins.

The bases that are present in DNA molecules are guanine, adenine, cytosine, and thymine. Each pair of bases in a DNA molecule codes for a specific amino acid.

Therefore, the sequence of bases carries the codes that are required for making a protein and these codes account for a specific amino acid.

Conclusion

Hence, statement II is the correct explanation for statement I.
