Question

Biolistices (gene - gun) is suitable for

• A. disarming pathogen vectors
• B. transformation of plant cells
• C. constructing recombinant $DNA$ by joining with vectors
• D. $DNA$ finger printing

Answer 1

The correct option is B transformation of plant cells

In genetic engineering, a gene gun or a biolistic particle delivery system, originally designed for plant transformation, is a device for delivering exogenous DNA (transgenes) to cells. The payload is an elemental particle of a heavy metal coated with DNA (typically plasmid DNA). This technique is often simply referred to as biolistics.

This device is able to transform almost any type of cell, including plants, and is not limited to transformation of the nucleus; it can also transform organelles, including plastids.

So the correct option is 'transformation of plant cells'.
