As we learn more about biotechnology, its big role in innovation and solving health and environmental issues becomes clear.
Understanding Genome Editing
Genome editing is a big step forward in genetic engineering. It lets us change an organism’s DNA with great precision. CRISPR technology is a key part of this field. It was first found in the late 1980s in prokaryotic genomes.
Researchers then found the CRISPR-associated (Cas) proteins. The Cas9 enzyme is now crucial for editing genes by cutting and changing specific DNA parts.
In 2012, scientists Jennifer Doudna and Emmanuelle Charpentier showed CRISPR-Cas9 could edit DNA in living things. Their work won them the 2020 Nobel Prize in Chemistry. Then, Feng Zhang and his team showed CRISPR could work in mammals, making it useful for editing complex organisms.
The CRISPR-Cas9 system uses guide RNAs (gRNAs) to guide the Cas9 enzyme to certain DNA spots. This method, along with the cell’s repair processes, allows for precise changes. It can fix genetic mutations that cause diseases.
Genome editing has many uses. In farming, it helps make crops resistant to diseases and boosts production. In medicine, it could cure genetic disorders. These benefits show how powerful these techniques are.
Education programs, like strawberry DNA extraction, teach the practical side of genome editing. They help students understand and get excited about advanced biotechnology.
