Study Notes
Molecular Biology Techniques
- Gel electrophoresis is used to separate DNA fragments based on their size.
- Blotting techniques, such as Southern blotting, are used to transfer DNA fragments from a gel to a membrane, allowing for the detection of specific sequences using probes.
- Genetic engineering, also known as recombinant DNA technology, involves the manipulation of DNA to create new combinations of genetic material, enabling the introduction of desired traits into organisms.
