Dolly (sheep)
Dolly was born on 5 July 1996 and had three mothers: one provided the egg, another the DNA, and a third carried the cloned embryo to term. She was created using the technique of somatic cell nuclear transfer, where the cell nucleus from an adult cell is transferred into an unfertilized oocyte (developing egg cell) that has had its cell nucleus removed. The hybrid cell is then stimulated to divide by an electric shock, and when it develops into a blastocyst it is implanted in a surrogate mother. Dolly was the first clone produced from a cell taken from an adult mammal. The production of Dolly showed that genes in the nucleus of such a mature differentiated somatic cell are still capable of reverting to an embryonic totipotent state, creating a cell that can then go on to develop into any part of an animal. Dolly's existence was announced to the public on 22 February 1997. It gained much attention in the media. A commercial with Scottish scientists playing with sheep was aired on TV, and a special report in "Time" magazine featured Dolly the sheep. "Science" featured Dolly as the breakthrough of the year. Even though Dolly was not the first animal cloned, she received media attention because she was the first cloned from an adult cell.
Dolly Parton
She launched a television series, "The Dolly Show," but it was not a success. Parton made a cameo appearance as herself in "The Beverly Hillbillies" (1993), an adaptation of the long-running TV sitcom of the same name (1962–71). 
Parton has done voice work for animation for television series, playing herself in "Alvin and the Chipmunks" (episode "Urban Chipmunk", 1983) and the character Katrina Eloise "Murph" Murphy (Ms. Frizzle's first cousin) in "The Magic School Bus" (episode "The Family Holiday Special", 1994). She also has guest-starred in several sitcoms, including a 1990 episode of "Designing Women" (episode "The First Day of the Last Decade of the Entire Twentieth Century") as herself, the guardian movie star of Charlene's baby. She made a guest appearance on "Reba" (episode "Reba's Rules of Real Estate") portraying a real-estate agency owner and on "The Simpsons" (episode "Sunday, Cruddy Sunday", 1999). She appeared as herself in 2000 on the Halloween episode of Bette Midler's short-lived sitcom "Bette," and on episode 14 of "Babes," (which was produced by Sandollar Productions, Parton and Sandy Gallin's joint production company).
She made cameo appearances on the Disney Channel as "Aunt Dolly", visiting Hannah and her family in the fellow Tennessean, and real-life goddaughter, Miley Cyrus's series "Hannah Montana" (episodes "Good Golly, Miss Dolly", 2006, "I Will Always Loathe You", 2007 and "Kiss It All Goodbye", 2010). She was nominated for Outstanding Guest Actress in a Comedy Series.
