Answer: A transgenic animal is one whose chromosomes have been changed to allow foreign DNA to be inserted into its genes. Many transgenic animals are created to help us better understand how genes play a role in disease development. Transgenic animals, such as mice and rabbits, are being developed to assess vaccination safety before they are utilised in humans.
Transgenic animals are so named because their DNA has been modified, resulting in the presence and expression of a foreign gene. Transgenic animals are created and their genes are modified in order for them to produce pricey biological products.
