Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is true of transgenic organisms?
A
Transgenic organisms have genes from a different species
B
Transgenic organisms have genes from their same species
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Definition. Transgenic refers to an organism or cell whose genome has been altered by the introduction of one or more foreign DNA sequences from another species by artificial means. Transgenic organisms are generated in the laboratory for research purposes.

Detailed explanation-2: -Transgenic plants are plants that have had their genomes modified through genetic engineering techniques either by the addition of a foreign gene or removal of a certain detrimental gene [1]. A foreign gene inserted into a plant can be of a different species or even kingdom.

Detailed explanation-3: -The key difference between GMO and transgenic organism is that GMO is an organism that has an artificially altered genome, while the transgenic organism is a GMO that has an altered genome containing a DNA sequence or gene from a different species.

Detailed explanation-4: -A transgenic plant is a modified organism where genes are transferred from one organism to another through genetic engineering techniques. There are two techniques for introducing foreign genes into the plant cell genome. The first is through a vector. And the second is through the direct introduction of DNA.
