Question

The transgenic animals are those which have __________________.

• A. Foreign DNA in some of its cells
• B. Foreign DNA in all its cells
• C. Foreign DNA and RNA in some of its cells
• D. Foreign DNA and RNA in all its cells

Answer 1

The correct option is B Foreign DNA in all its cells

Transgenic animals are animals that have had a foreign gene deliberately inserted into their genome. Such animals are most commonly created by the micro-injection of DNA into the pronuclei of a fertilised egg which is subsequently implanted into the oviduct of a surrogate mother.

So, the correct answer is 'Foreign DNA in all its cells'
