Which of the following techniques involves the direct introduction of recombinant DNA into the nucleus of an animal cell?
Options
- ABiolistics
- BMicro-injection
- CHeat shock method
- DUse of disarmed Agrobacterium vectors
Correct answer
B. Micro-injection
Step-by-step solution
In the micro-injection technique, recombinant DNA is directly injected into the nucleus of an animal cell.
Biolistics or gene gun method is primarily used to introduce DNA into plant cells.
The heat shock method is used to make bacterial cells competent to take up recombinant DNA.
Disarmed Agrobacterium vectors are used to deliver genes of interest into plant cells.
