Detailed explanation-1: -N E W Y O R K, Sept. 7, 2001–A study confirms what scientists had always thought about Dolly the sheep: If you want to be really picky, you can say she’s not completely identical genetically to the ewe she was cloned from.
Detailed explanation-2: -Dolly was cloned from a mammary gland cell taken from an adult Finn Dorset ewe. Wilmut and his team of researchers at Roslin created her by using electrical pulses to fuse the mammary cell with an unfertilized egg cell, the nucleus of which had been removed.
Detailed explanation-3: -So the correct answer is “The mother from which nucleated udder cell was taken"
Detailed explanation-4: -Dolly was an identical twin of the mother who gave her her DNA. But Dolly was six years younger. However, Dolly and her mother were not identical in every way. Since Dolly and her “DNA mother” had different experiences, they were different in many ways.
