Answer:
➡️The idea to clone human beings originated in 1996 when the first cloned sheep was created by adult cell nuclear transfer.
➡️In 1996 scientists from Roslin Institute in Edinburgh, with its financial partners PPL therapeutics Inc., created a sheep clone, Dolly.
➡️Nuclear transplantation steps taken by the scientists to create Dolly:
➡️They took an under cell of a six-year-old ewe.
➡️Transplanted the nucleus containing the DNA into an unfertilised egg of a second sheep. The nucleus of the unfertilised egg had previously been removed.
➡️The cell and egg were fused with electric pulses.
➡️The egg began to divide normally and developed into an embryo.
➡️The embryo was then implanted into a third, surrogate sheep who gave birth to a lamb, genetically identical twin of the sheep from which the mammary cell were taken.
➡️The lamb born was named Dolly.
