Consider the following statements and identify the correct statements
I. While using genes encoding antibiotic resistence as selectable markers, such genes are selected for which host is naturally resistant
II. Restriction site of PvuII is present in gene
III. Ti plasmid is most widely used in gene transfer in all plants
IV. Retroviruses are directly used (unchanged) to deliver desirable genes into animal cells
