Question

The following are the events in the formation of the first cloned animal – the sheepDolly.a) Removal of haploid nucleus from the ovum.b) Implantation of ovum with diploid nucleus into the surrogate mother.c) Collection of udder cell from the sheep.d) Injection of diploid nucleus of udder cell into the enucleated ovum.e) Development of a young clone.The correct sequential order of these events is __________ .i) abcde ii) cabed iii) cadbe iv) edcba

Answer 1

“Cadbe” can be the sequence of events in the formation of the first cloned animal-the sheep Dolly.

“C” collection of udder cell from the sheep, “a” removal of the haploid nucleus from the ovum, “d” injection of diploid nucleus of the udder cell into the enucleated ovum, “b” implantation of ovum with diploid nucleus into the surrogate mother “e” Development of a young clone.

With respect to the problem statement, the option iii.) is the correct one.
