Question

The process of transformation in which the cells take up the foreign gene without the help of vector is known as

• A. Direct gene transfer
• B. Electroporation
• C. Microinjection
• D. None of the above

Answer 1

The correct option is A Direct gene transfer

The desired gene of the recombinant DNA can be incorporated into the host cell by different methods. The method in which there is no involvement of the vector in the gene transfer is known as the direct gene transfer method. Different chemicals like PEG and calcium phosphate are used to make the cells competent which can take up the recombinant DNA.

Thus, the correct answer is option A.
