Examples of Transgenic Animals
Following are the example of transgenic animals:
Transgenic mice
By injecting DNA into the oocytes or the one-two-celled embryos which were taken from the female mice these transgenic animals are developed. After it is injected into the DNA then the embryo is implanted into the uterus of the female receptor.
Dolly Sheep
It was the first mammal that was cloned from an adult cell. The udder cell of a six-year-old girl Finn Dorset white sheep was injected into an unfertilized egg which was from a Scottish Blackface ewe whose nucleus has been removed. The cell was made to fuse by the electrical pulses and after the fusion of the nucleus cell with the egg the embryo was cultured for 6 to 7 days. It was implanted into another Scottish Blackface ewe which gave birth to transgenic sheep named Dolly.
Transgenic Animals Notes – Biotechnology And Its Application
CBSE Class 12- Biotechnology And Its Application – Transgenic Animals: When a foreign gene inserts into the genome of the animals to alter its DNA or the animals with a modified genome are Known as Transgenic Animals. It is a method that helps to improve the genetic traits of targeted animals. Transgenic animals are also called genetically modified organisms.
