Read the following statement regarding DNA recombinant technology. Identify the statements that are true and false and select the appropriate option.
I. Selectable marker helps in identifying and eliminating non-transformants and selectively permitting the growth of the transformants.
II. Plasmids have the ability to replicate within bacterial cells independent of the control of chromosomal DNA making it a suitable cloning vector.
III. The DNA fragments for isolation can be separated by a technique known as thin-layer chromatography.
IV. A technique where cells are bombarded with high velocity micro-particles of Au or W coated with DNA is known as micro-injection.
