Question

Gene recombinant technology is used for

• A. Vectorless gene transfer into target cell.
• B. Vector based gene transfer into target cell.
• C. Direct transfer of DNA protein complex.
• D. Liposome base direct gene transfer into target cell.

Answer 1

Answer: (B)

Vector based gene transfer into target cell.

• In molecular cloning, the DNA molecules are used as the vector to transfer the desired gene into the host cell.
• Desired gene gets incorporated into the host genome and then replicates to express the gene.
• The vectors are constructed using the recombinant DNA technology method.
• Vectors are of different types based on their size and the number of genes they can carry. The most common vectors are the plasmids.

Thus, the correct answer is option B.
