Read Biotech in Diagnosis and Treatment
Medical biotechnology can diagnose disease, replace a missing product or deliver a therapeutic molecule.
Medical Biotechnology is the central idea in this question pattern. Identify the condition in the stem before applying the method below.
Detect targets
ELISA uses an enzyme-linked colour reaction to detect antigen or antibody. A nucleic-acid probe detects a complementary sequence; a mutation in the probe-binding region may remove the signal.
Treat inherited disease and infection
ADA deficiency can be managed with enzyme replacement or transplantation; gene therapy approaches depend on the target cells and may need repeated treatment. Recombinant hepatitis-B vaccine is a yeast-produced subunit vaccine, not a DNA vaccine.
Use therapeutic proteins
Recombinant products include insulin, growth hormone, vaccines and streptokinase. Human-sequence products reduce but do not categorically eliminate immune reactions; inspect each statement rather than generalising.

- ✓ELISA → enzyme-generated colour.
- ✓Probe hybridisation needs complementary sequence.
- ✓Hepatitis-B recombinant vaccine → yeast-made subunit vaccine.
- ✓Streptokinase → clot-buster.
A recombinant vaccine is not automatically a DNA vaccine.
