In 1997, a(n) lamb named Dolly was introduced to the world. She was a(n) clone, or living thing that receives its DNA from one parent. Dolly’s DNA didn’t come from sex cells. Instead, it came from the body cell of a female sheep. A Scottish scientist named Ian Wilmut grew this cell. He stopped the body cell from making a(n) copy of its chromosomes. Then he combined it with an egg cell and applied a small amount of electricity. The cell began to divide as though it had joined with a(n) sperm cell. A few days later the egg cell divided into a(n) ball of cells. The ball of cells was then placed inside a(n) female sheep.
