Respuesta :
Transgenic plants are plants in which DNA from another species has been introduced into the plant's genome. In order to identify plants that integrate a transgene, we need the termination sequence. A transgenic plant differs from a hybrid plant because hybrids are produced through sexual reproduction between sexually compatible parents whereas transgenic plants are created by transferring the specific genetic material governing a particular trait from a non-compatible organism.
Ans. (c). marker gene.
A transgene is foreign gene or DNA molecule, which has been transferred to a host organism, naturally or artificially. The host cell, integrated with transgene is known as recombinant cell.
A marker gene is used to check whether the transgene has been successfully integrated into the DNA of host cell. So, marker gene is a necessary component to identify plants, integrated with a transgene.
Thus, the correct answer is option (c).
