Which of the following statements accurately describes transgenic animals?
All cells of transgenic animals contain foreign RNA.
Some cells of transgenic animals contain foreign DNA.
All cells of transgenic animals contain foreign DNA.
Both foreign RNA and DNA are present in transgenic animals.
Transgenic animals are genetically modified organisms that have had foreign genes introduced into their genome. These foreign genes are typically introduced through the integration of foreign DNA into the animal's cells. Therefore, option 3 stating that transgenic animals have foreign DNA in all their cells is the correct statement.
