Bio Question - Cloning?

Question

Can you help us with this?

What are the general steps in cloning? Short answer (3-6 sentences) please! Fairly simple, as well. This is for a 9th grade biology class.

Answer 1

There are different methods to cloning. But the 'Reproductive Cloning' is the most publically exposed one. i.e Dolly the sheep was cloned using reproductive cloning.

Imagine a chicken egg, it consist of the egg yoke and egg white which is inside the egg shell.

It is essentially the same with most species' eggs. The egg yoke (which is the nucleus) contains all (or almost) the genetic materials, where as the egg white and egg shell contains significantly less.

Here comes the general steps:
1) Remove all the genetic material (i.e. the nucleus). Now you have an egg without any genetic infomation.
2) Transfer the 'donor's' genetic material (the new nucleus) into the egg
3) The 'new' egg with the new genetic information now must be treated with chemicals or electric shock to trigger cell division.
4) Once the egg divides into certain stage, it is then transplanted into a uterus. (In the case of Dolly the Sheep, the egg is transfered to the uterus of a female sheep).
5) The egg will continue to grow and develope fully, based on the donor's DNA information.
6) The host will then give birth to a clone of the DNA donor.

This unfortunately (or fortunately) isn't as successfully on human eggs.

Hope this helps.

Answer 2

well first you have an unfertilized egg.
1)Find a female specie of what u want to clone
2)Place the nuclei of the organism into the egg of this female specie
3)As the female gives birth the nuclei will split causing it to give birth to a clone of the animal which the nuclei was extracted.

The first organism to be cloned was a sheep named dolly. This was how they cloned her.
