The purpose of using a diploid nucleus of a somatic cell as the nuclear donor in SCNT is .. to ensure that the embryo inherits one functional copy each of the genes regulated in a gamete of-origin specific manner, for normal embryonic development to occur. because the somatic cells are robust as they live long as compared to embryonic cells, and have long term gene activation. so that both the X and Y chromosomes are expressed, for balanced gene regulation to ensure that both copies of all genes on the two sets of chromosomes are expressed, as this is needed for normal embryonic development to occur. because these cells are easy to obtain compared to egg cells Farmal marks will be awarded if all correct ones are not selected. Correct answers will be released three working days after the quiz has finished. Question 2 1 pts The principle(s) of expressing a foreign protein from an animal into the milk of a mammal involvefs) -. using a vector that can transfect mammalian cells the gene to be cloned must have mammary gland specific expression in the original donor animal that it came from all of the given answers apply cloning the CDNA of the foreign gene in front of a mammary gland specific promoter using a promoter that is functional only in the mammary gland
