Regarding the vectors used in genetic engineering, evaluate the following statements:

I. Bacterial plasmids are used as cloning vectors for the gene of interest for genetic transformation in plants.
II. Plasmids are dependent on chromosomal DNA for replication, and are frequently manipulated in the gene transformation process.
III. To be a good cloning vector, a plasmid must have a replication origin, cleavage sites for restriction endonucleases, and a gene that encodes resistance to an antibiotic.
