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

DNA formed by combining genetic material from different organisms

CRISPR-Cas9

A gene-editing technology that allows precise changes to DNA sequences

Monoclonal antibody

An antibody produced from a clone of a single immune cell; highly specific to one antigen

PCR

Polymerase chain reaction; a technique to amplify specific DNA sequences
