Answer:
DNA carried on bacterial plasmids are generally not integrated into the genome. The DNA carried on Ti plasmids are usually integrated into the plant genome, meaning the genes are stably expressed
Explanation:
A single strand of the T-DNA from the Ti plasmid enters the plant cell through a transport channel and into the nucleus, where it is integrated into the plant's DNA. In contrast, the DNA introduced into bacteria on bacterial plasmids remains extra-chromosomal
