What is the mechanism for transforming normal plant cells into tumor cells?
Options
- AMicro-injection
- BBiolistics
- CInfection by a disarmed pathogen
- DTreatment with a divalent cation
Correct answer
C. Infection by a disarmed pathogen
Step-by-step solution
This is not the only way to introduce alien DNA into host cells. In a method known as micro-injection, recombinant DNA is directly injected into the nucleus of an animal cell. In another method, suitable for plants, cells are bombarded with high velocity micro-particles of gold or tungsten coated with DNA in a method known as biolistics or gene gun. And the last method uses ‘disarmed pathogen’ vectors, which when allowed to infect the cell, transfer the recombinant DNA into the host .
