MAN GENETICS: CONCEPTS AND APPLICATIONS
13th Edition by Ricki Lewis | Complete MCQs with Rationales
PART ONE: INTRODUCTION
Chapter 1: The Information in a Human Genome (Questions 1–12)
1. The complete set of genetic instructions in a cell is called the:
A) Genotype
B) Genome
C) Karyotype
D) Phenotype
Answer: B
The genome is the complete set of genetic instructions in a cell, including all genes and
noncoding DNA. The genotype refers to the specific alleles present, while the phenotype is
the observable characteristics.
2. Which of the following best describes the relationship between genes and genomes?
A) Genes are larger than genomes
B) Genomes are composed of genes only
C) Genes are segments of DNA within the genome
D) Genomes are found only in reproductive cells
Answer: C
Genes are specific segments of DNA that encode proteins or functional RNA molecules. The
genome encompasses all DNA, including genes and noncoding regions.
3. The study of genetics at the level of populations is called:
, Page 2 of 69
A) Molecular genetics
B) Transmission genetics
C) Population genetics
D) Cytogenetics
Answer: C
Population genetics studies allele frequencies and how they change over time within
populations. Molecular genetics focuses on DNA and gene function, while transmission
genetics examines inheritance patterns.
4. Which application of genetics involves analyzing an individual's DNA to predict drug
response?
A) Gene therapy
B) Pharmacogenomics
C) Genetic counseling
D) Cytogenetics
Answer: B
Pharmacogenomics uses genetic information to predict how an individual will respond to
specific medications, enabling personalized drug selection and dosing.
5. The Human Genome Project was significant because it:
A) Created the first genetically modified organism
B) Sequenced the entire human genome
C) Developed the first gene therapy
D) Discovered the structure of DNA
Answer: B
The Human Genome Project (1990–2003) was an international effort that successfully
sequenced the entire human genome, providing a foundation for modern genomics.
6. Bioinformatics is best defined as:
A) The study of genetic diseases
B) The use of computational tools to analyze biological data
C) The study of protein structure
D) The development of new drugs
Answer: B
, Page 3 of 69
Bioinformatics applies computational and statistical methods to analyze and interpret
biological data, including DNA sequences, protein structures, and gene expression data.
7. Which "level of genetics" focuses on the function of individual genes at the molecular
level?
A) Population genetics
B) Organismal genetics
C) Molecular genetics
D) Cellular genetics
Answer: C
Molecular genetics focuses on the structure and function of genes at the molecular level,
including DNA replication, transcription, and translation.
8. Personalized medicine uses genetic information to:
A) Treat all patients with the same drug
B) Tailor medical treatment to an individual's genetic profile
C) Avoid the use of all medications
D) Replace surgery with gene therapy
Answer: B
Personalized medicine (precision medicine) uses an individual's genetic information to select
the most effective treatments and avoid adverse drug reactions.
9. Which of the following is an example of a global perspective on genomes?
A) Comparing human genomes across different populations
B) Studying bacterial genomes only
C) Ignoring genetic variation
D) Focusing on a single individual
Answer: A
A global perspective on genomes involves comparing genetic variation across human
populations to understand migration patterns, disease susceptibility, and evolutionary
relationships.
10. The term "genetic determinism" refers to the belief that:
, Page 4 of 69
A) Genes determine all traits
B) Environment has no effect on traits
C) Genes and environment interact
D) Only some traits are genetic
Answer: A
Genetic determinism is the belief that genes alone determine traits, ignoring environmental
influences. Modern genetics recognizes that most traits result from gene-environment
interactions.
11. Which of the following is NOT a level of genetics mentioned in the textbook?
A) Molecular genetics
B) Transmission genetics
C) Quantum genetics
D) Population genetics
Answer: C
The levels of genetics discussed include molecular, cellular, organismal, transmission, and
population genetics. Quantum genetics is not a recognized level in the textbook.
12. The "Big Picture" feature in each chapter is designed to:
A) Provide practice problems
B) Encapsulate the overall theme of the chapter
C) List key terms
D) Provide historical context only
Answer: B
The Big Picture feature encapsulates the overall theme of each chapter, helping students
understand the main concepts before diving into details.
Chapter 2: Cells (Questions 13–24)
13. Which organelle contains the genetic material in eukaryotic cells?
A) Mitochondria
B) Nucleus
C) Ribosome
D) Golgi apparatus
Answer: B
