Human proteins can be produced in the milk or semen of farm animals. True or false?
(a) True
(b) False, proteins cannot be produced in milk
(c) False, proteins cannot be produced in semen
(d) False, animals are not used for protein production
Answer (a) : Several human genes have been successfully transferred in animals and are expressed in the mammary tissue; the protein is secreted in milk from where it is easily harvested. These genes can also be made to express in reproductive tissues and thus proteins can also be harvested from semen ejaculate of male organisms. E.g., hGH is being produced from a transgenic mouse variety’s semen.
