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. {:(,I,II,III,IV),(1,"False","False","True","True"),(2,"True","True","False","False"),(3,"True","True","True","True"),(4,"False","False","True","False"):}
