Biotechnology Principles and Processes

• Agrobacterium tumefaciens is a significant tool in genetic engineering, specifically utilized for its ability to transfer genes into plant cells, enabling scientists to create genetically modified organisms (GMOs) efficiently.
• Restriction endonucleases are enzymes that cut DNA at specific sites.
• Genetic engineering involves manipulating the genotype of an organism by introducing foreign genes.
• Polymerase chain reaction (PCR) is a technique used for DNA amplification.
• DNA probes are used to locate specific genes.
• Taq polymerase is an enzyme used in PCR.
• Plasmids are small circular DNA molecules that are used as vectors in genetic engineering.
• Transgenic organisms contain genes from another species.
• Vectors are used to transfer genes into cells.
