The Ti Plasmid Is Crucial to Genetic Engineering in Plants

The Ti plasmid is crucial to genetic engineering in plants.The key feature of the Ti plasmid is that it

A) uses the CRISPR/Cas system to edit the plant genome.
B) only replicates in bacterial cells.
C) uses zinc finger nucleases (TALENs) to edit the plant genome.
D) leads to insertion of a part of the plasmid DNA into the plant cell chromosomal DNA.
E) acts as an artificial chromosome within plant cells.
