Medical Biotechnology
Medical biotechnology uses biological systems and living organisms to develop products and technologies that improve human health, including gene therapy, vaccines, and diagnostic tools.
What You Need to Know
Key Concept Diagram
Recombinant DNA technology inserts genes from one organism into another to produce useful proteins
CRISPR-Cas9 is a gene-editing tool that can precisely modify DNA sequences
Monoclonal antibodies are identical antibodies produced from a single immune cell, used in cancer treatment
PCR (polymerase chain reaction) amplifies small amounts of DNA for diagnostic testing
mRNA vaccines instruct cells to produce a protein that triggers an immune response
Key Vocabulary
Recombinant DNA
