For transformation, micro-particles coated with DNA to be bombarded from gene gun are made up of

A

silver or platinum

B

platinum or zinc

C

silicon or platinum

D

gold or tungsten

Text Solution

Verified by Experts

The correct Answer is:
d
Biolistics gene gun is a direct or vectorless way used to introduce alien DNA into host cells. In this method of gene transfer, high velocity microparticles of gold or tungsten, coated with DNA are bombarded on the plant cells.
