(D) Microinjection

Method involving entry of high velocity gold microparticles coated with DNA into plant cell is

Select the wrong statement (a) Presence of chromogenic substrate gives blue color colonies if the plasmid in the bacteria does not have an insert (b) Retroviruses in animals have the ability to transform normal cells into cancerous cells (c) In microinjection, cells are bombarded with high velocity microparticles of gold or tungsten coated with DNA (d) Since DNA is a hydrophilic molecule it cannot pass through cell membranes

Assertion: In biolistics method, cells are bombarded with high velocity micr-particles of gold or tungsten coated with DNA Reason :It is suitable for plant cells

In biolistic method of gene trasfer, the microparticles coated with foreign DNA are bombarded into target cells at a very high velocity. These microparticles are made up of 1) silver or tungsten 2) arsenic or silver 3) gold or tungsten 4) none of these

For transformation, micro-particles coated with DNA to be bombarded from gene gun are made up of (a) silver or platium (b) platinum or zinc (c) silicon or platinum (d) gold or tungsten

For which subatomic particle the ratio of charge and mass would be greater. (A) Proton, (B) Alpha particle, (C) Neutron, (D) Electron

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"):}
