Understand the role of the Ti plasmid in nature: The Ti plasmid is found in the bacterium Agrobacterium tumefaciens, which naturally infects plants and causes crown gall disease.
Recognize the key feature of the Ti plasmid: It has the ability to transfer a segment of its DNA, known as T-DNA, into the genome of plant cells, which is crucial for genetic engineering.
Consider the implications of gene transfer: This natural ability to integrate foreign DNA into plant genomes makes the Ti plasmid a powerful tool for introducing new genes into plants, allowing for the development of genetically modified plants.
Evaluate other features: While the Ti plasmid has other characteristics, such as its ability to replicate independently, these are not directly related to its usefulness in genetic engineering of plants.
Conclude the significance: The ability to transfer genes to plant cells is the primary reason the Ti plasmid is utilized in genetic engineering, as it facilitates the stable integration of desired traits into plant genomes.
