Chapters 1–20 + Applications A, B, C
CHAPTER 1: THE MOLECULAR BASIS OF HEREDITY,
VARIATION, AND EVOLUTION
Multiple Choice Questions
1.1 Which of the following best describes the central dogma of molecular biology?
A) DNA → Protein → RNA
B) RNA → DNA → Protein
C) DNA → RNA → Protein
D) Protein → RNA → DNA
Answer: C
Explanation: The central dogma states that genetic information flows from DNA to RNA
(transcription) to protein (translation). While exceptions exist (e.g., reverse transcription), the
fundamental flow is DNA → RNA → Protein.
Difficulty: Easy
Learning Objective: Describe the central dogma of molecular biology.
Section Reference: 1.2 The Central Dogma of Molecular Biology
1.2 What are the three main activities that genes carry out?
A) Replication, transcription, and mutation
B) Replication, expression, and variation
C) Transcription, translation, and recombination
D) Replication, recombination, and repair
Answer: B
Explanation: Genes must be replicated faithfully (replication), used to produce functional
products (expression), and undergo changes that introduce genetic diversity (variation through
mutation and recombination).
Difficulty: Easy
, Learning Objective: Identify the three main activities of genes.
Section Reference: 1.1 The Molecular Basis of Heredity
1.3 Nucleotides, the building blocks of DNA and RNA, consist of which three components?
A) A sugar, a phosphate group, and a nitrogenous base
B) An amino acid, a phosphate group, and a sugar
C) A sugar, a sulfate group, and a nitrogenous base
D) A fatty acid, a phosphate group, and a nitrogenous base
Answer: A
Explanation: Each nucleotide contains a five-carbon sugar (deoxyribose in DNA, ribose in RNA),
a phosphate group, and a nitrogenous base (purine or pyrimidine).
Difficulty: Easy
Learning Objective: Describe the chemical composition of nucleotides.
Section Reference: 1.2 DNA and RNA Structure
1.4 Which of the following is a pyrimidine base found in DNA but NOT in RNA?
A) Adenine
B) Guanine
C) Thymine
D) Uracil
Answer: C
Explanation: Thymine is a pyrimidine found in DNA. In RNA, thymine is replaced by uracil.
Adenine and guanine are purines found in both DNA and RNA.
Difficulty: Easy
Learning Objective: Distinguish between DNA and RNA nucleotide composition.
Section Reference: 1.2 DNA and RNA Structure
1.5 Chargaff's rules state that in double-stranded DNA:
A) A = G and C = T
B) A = T and G = C
C) A = C and G = T
D) A + T = G + C always
Answer: B
Explanation: Chargaff's rules establish that in double-stranded DNA, the amount of adenine
equals thymine (A = T) and the amount of guanine equals cytosine (G = C), reflecting Watson-
Crick base pairing.
Difficulty: Easy
Learning Objective: State Chargaff's rules and their significance.
