Question

The first mammal cloned Dolly was created by :
A. Ian Wilmut
B. T.H Morgan
C. Robert Briggs
D. Thomas King

Answer 1

Hint: Clones are genetically identical to each other. Naturally, clones are produced by asexual reproduction. In DNA cloning techniques clones are produced identical to the parent cell from which the mammary cell is taken.

Complete answer: Dolly, the cloned sheep was produced by Ian Wilmut. Genetic clones of clones are the organisms that are genetically identical to one another. Mammalian cloning technology leads to the production of dolly, a female Dorset sheep which was a clone of an adult mammal. Dolly was cloned by using a mammary gland cell of adult Finn Dorset ewe sheep. An unfertilized egg cell without a nucleus was fused with a mammary cell. After that this fused cell divided. This technique of clone production is called somatic cell nuclear transfer. Dolly had functional organs and lived from 1996-2003. This sheep was identical to the characters of the sheep whose mammary cell was taken. Also, Dolly was healthy and fertile. Dolly was created by Ian Wilmut in 1996 in Scotland. It lived from 1996-2003.
Hence, the correct answer is Option A.

Note: Using the process of nuclear transfer Dolly a sheep was cloned from an adult somatic or mammary cell. Dolly was a healthy, fertile sheep that gave birth to six lambs. Also, this sheep was genetically identical to the parent Finn dorset sheep.
