Study Notes
Genetic Concepts and Techniques
- Cloning is the process of making identical copies of genes.
- Vectors are used to carry foreign DNA in recombinant DNA technology, facilitating the insertion and expression of the gene in the host organism.
Genetically Modified Organisms
- Organisms that have had a foreign gene inserted into their genome are known as genetically modified organisms (GMOs).
- Examples of GMOs include corn, potato, soybean, and cotton, which produce traits such as pest resistance or herbicide tolerance as a result of genetic modification.
Enzymatic Tools in Genetics
- Restriction enzymes are commonly referred to as "molecular scissors" due to their ability to cut DNA at specific sequences, making them essential tools in genetic engineering.
