Question

Name the technique which was used in producing ‘Dolly’ the sheep.

Answer 1

Answer:

for producing dolly first the nucleus of the cell of the egg of Swedish Brown sheep was removed and replaced by the diploid cell of mammary gland of a white sheep and was again implanted in the Swedish Brown sheep. this resulted in the birth of dolly which was identical to the white sheep

Answer 2

The technique which was used in producing ‘Dolly’ the sheep is Somatic cell nuclear transfer.

Explanation:

• SCNT is a laboratory strategy to develop embryo from body cell and egg cell.
• In this technique, the egg cell is implanted in donor nucleus of body cell. It is used in reproductive and therapeutic cloning.
• Dolly is a cloned sheep by Ian Wilmut.
• The egg from black faced sheep is fused with body (somatic) cell from white faced sheep.
• The fusion and division of cell takes place with supply of suitable amount of voltage.
• The divided call is placed in uterus of black faced sheep.
• After 10 months, a white faced lamb is produced. Dolly is identical to its nucleus donor.
