MOLECULAR DIAGNOSTICS 3RD EDITION
BUCKINGHAM TEST BANK PRACTICE TEST
BANK 2026 TESTED QUESTIONS WITH
ANSWERS GRADED A+
⩥ What is genetics? Answer: The study of genes, genetic variation and
heredity in organism.
⩥ What is genomics? Answer: The study of the genomes of organisms,
initially revealing static gene sequences and enabling functional
genomics.
⩥ What is transcriptomics? Answer: -The study of the complete set of
RNA transcripts of a cell, typically referring to just mRNA, but may
refer to all RNA.
-Analysing gene expression patterns to identify disease states and pre-
symptomatic changes.
⩥ What is proteomics? Answer: -The large-scale study of organisms.
-Proteins are functional biomarkers; proteomics reveals disease
mechanisms beyond gene expression.
⩥ What is metabolomics? Answer: -The large-scale study of small
molecules.
,-This reflects real-time metabolic state influenced by genetics and
environment, aiding biomarker discovery.
⩥ What is diagnostics? Answer: Determining a disease of condition.
⩥ What is pharmacogenomics? Answer: The study of how a persons
genome affects the response to treatment. This enables targeted therapies
and personalised medicine.
⩥ What is personalised/precision medicine? Answer: Personally tailored
treatment based on predicted response or risk of disease.
⩥ Why is Mdx better than traditional diagnostics? Answer: Often faster,
more sensitive and more specific (detects diseases at molecular level.
⩥ What major concerns exist around Mdx? Answer: Ethical/social/legal
issues (privacy, consent, predictive testing), plus technical issues
(contamination, interpretation, access).
⩥ What is driving growth in the molecular diagnostics (MDx) market?
Answer: -Biotechnology is the fastest-growing field in modern clinical,
research, and forensic laboratories.
-Ongoing research is driving the development of new diagnostic tests,
while the MDx market continues to expand due to growing demand for
personalised, targeted therapies.
, ⩥ Why is molecular diagnostics considered a major breakthrough in
clinical medicine? Answer: -Molecular diagnostics has become an
integral part of the clinical laboratory, enabling a shift from basic
molecular research to practical diagnostic tests.
-Advances in molecular biology have revolutionised biomedical
research, fundamentally changing healthcare by improving disease
detection and management.
-Although MDx has applications beyond medicine, such as agriculture
and environmental science, its primary impact has been in medical
research and clinical practice.
⩥ Why has molecular diagnostic testing grown rapidly over the past
decade? Answer: Due to breakthroughs in basic science (e.g. Human
Genome Project) and applied technologies, with growth rates of ~10-
20% per year.
⩥ What early discoveries laid the foundation for molecular diagnostics?
Answer: DNA structure (Watson & Crick, 1953), understanding
transcription/translation, and the recombinant DNA revolution of the
1970s.
⩥ Which technologies enabled the rise of molecular diagnostics?
Answer: DNA cloning, hybridisation, automated DNA sequencing
(1977), and PCR (1985).
