Cloning
Dolly, a Finn-Dorset ewe, was the first mammal to have been successfully cloned from an adult somatic cell. Dolly was formed by taking a cell from the udder of her 6-year old biological mother. Dolly's embryo was created by taking the cell and inserting it into a sheep ovum. It took 434 attempts before an embryo was successful. The embryo was then placed inside a female sheep that went through a normal pregnancy. She was cloned at the Roslin Institute in Scotland by British scientists Sir Ian Wilmut and Keith Campbell and lived there from her birth in 1996 until her death in 2003 when she was six. She was born on 5 July 1996 but not announced to the world until 22 February 1997. Her stuffed remains were placed at Edinburgh's Royal Museum, part of the National Museums of Scotland.
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.
