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

Answer: (B)

Foreign DNA in all its cells

A transgenic animal is that animal which carries the foreign gene. Foreign gene is inserted into the genome by the process of recombinant DNA technology and such DNA is called as recombinant DNA which is then transferred into embryos prior to birth. Each transferred gene is assimilated by the genetic material or chromosomes of the embryo and subsequently can be expressed in all tissues of the resulting animal

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