1. What is molecular diagnostics? - Correct Answer: -A family of
techniques used to analyse biological markers, such as mutations, in an
individuals genetic code (genome), to analyse how their cells express their
genes as proteins (proteome), or the presence of biomolecules from
pathogenic microorganisms in infectious disease.
-MDx offers more rapid and accurate insight with greater sensitivity and
specificity than traditional diagnostic methods.
-MDx allows the detection and monitor disease (diagnostics), assess risk
(prognostics), and personalise therapies by determining which treatments
will work best for an individual patient (pharmacogenomics).
2. What is genetics? - Correct Answer: The study of genes, genetic
variation and heredity in organism.
3. What is genomics? - Correct Answer: The study of the genomes of
organisms, initially revealing static gene sequences and enabling functional
genomics.
4. What is transcriptomics? - Correct 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.
5. What is proteomics? - Correct Answer: -The large-scale study of
organisms.
-Proteins are functional biomarkers; proteomics reveals disease
mechanisms beyond gene expression.
6. What is metabolomics? - Correct Answer: -The large-scale study of small
molecules.
-This reflects real-time metabolic state influenced by genetics and
environment, aiding biomarker discovery.
7. What is diagnostics? - Correct Answer: Determining a disease of
condition.
8. What is pharmacogenomics? - Correct Answer: The study of how a
persons genome affects the response to treatment. This enables targeted
therapies and personalised medicine.
9. What is personalised/precision medicine? - Correct Answer: Personally
tailored treatment based on predicted response or risk of disease.
10.Why is Mdx better than traditional diagnostics? - Correct Answer: Often
faster, more sensitive and more specific (detects diseases at molecular level.
, 11.What major concerns exist around Mdx? - Correct Answer:
Ethical/social/legal issues (privacy, consent, predictive testing), plus
technical issues (contamination, interpretation, access).
12.What is driving growth in the molecular diagnostics (MDx) market? -
Correct 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.
13.Why is molecular diagnostics considered a major breakthrough in clinical
medicine? - Correct 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.
14.Why has molecular diagnostic testing grown rapidly over the past decade? -
Correct Answer: Due to breakthroughs in basic science (e.g. Human
Genome Project) and applied technologies, with growth rates of ~10-20%
per year.
