Why was Dolly(世界上的第一只克隆羊) important? The sheep was the first mammal(哺乳动物) to be cloned using DNA taken from an adult cell. Previously(以前), animals had only been cloned using embryo cells which already have the potential(潜力) to become a complete embryo in its own right(继承父母的). The big breakthrough with Dolly was to make a clone from an ordinary, adult cell - in this case from a female goat's udder(乳房).

May bring some new diseases which is It can be abused by some dangerous organizations. A big hammer to traditional family structure and relationship. Hurt those who are cloned.
What is cloning? Cloning is the creation of cells or whole animals using DNA from a single "parent", bypassing the normal reproductive process. The clone has the same DNA to the parent. The generalized clone refers to every crowd from a same ancestor, passing through asexual propagation

Thank you!
How are clones created? The most common process takes DNA from one cell and puts in a hollowed-out(挖空的；掏空的) egg. Chemicals and electricity are then used to encourage the new DNA to fuse with(与…合并) the egg and develop into an embryo(胎儿). This technique is called nuclear transfer(核迁移).

Is clone good or not?
Research advances over the past decade have told us that, with little work, we humans can clone just about anything we want, from frogs to monkeys and probably even ourselves!
“克隆” is the transliteration of "clone", scientists call the operation which reproduces the animals of artificial heredity as clone and this biological technology is called clone technology.
