Cloning Colly- A body cell was removed from sheep #1 and the nucleus and its DNA was removed from the body cell. An egg (gamete) was removed from sheep #4 and its nucleus from the egg was discarded. The nucleus and its DNA from sheep 1 is inserted into the egg of sheep 4 and stimulated to grow. The resulting diploid cell mass is inserted into the uterus of sheep #9. Sheep #9 gives birth to Dolly? Which sheep is Dolly a clone of/

I know the answer is sheep number 1 but I'm not sure how to explain why it is sheep number one and why it isn't sheep #4 or #9...please help

its actually cloning Dolly

It is clonnig dolly

Dolly the sheep is a clone of sheep #1. Let's break down the process to understand why.

In the cloning process, a body cell was taken from sheep #1. This body cell contained the complete set of DNA of sheep #1. The nucleus of this body cell, which holds the DNA, was removed.

On the other hand, an egg (gamete) was extracted from sheep #4. The nucleus of this egg, along with its DNA, was discarded.

Next, the nucleus from sheep #1, which contains its DNA, was inserted into the empty egg of sheep #4. This resulted in a diploid cell, which means it had a complete set of chromosomes, just like a regular body cell.

This diploid cell mass was then inserted into the uterus of sheep #9. Sheep #9 acted as a surrogate mother and provided the necessary environment for the cloned embryo to grow and develop.

Finally, sheep #9 gave birth to Dolly, who is a clone of sheep #1. This is because the nucleus and its DNA, which determines the genetic information, came from sheep #1.

Thus, Dolly inherited the exact same genetic information as sheep #1, making her a clone of sheep #1.

Dolly is a clone of sheep number 1. To understand why, let's break down the process of cloning and specifically the steps involved in creating Dolly.

1. Body cell removal: A body cell was taken from sheep #1. This body cell contains a complete set of the sheep's DNA, which essentially serves as a blueprint for the entire organism.

2. Nucleus and DNA removal: The nucleus, along with its DNA, is extracted from the body cell of sheep #1. The nucleus holds the genetic material of the sheep, including all the instructions required for proper development and functioning.

3. Egg removal: An egg (gamete) is taken from sheep #4. However, the nucleus from this egg is discarded, meaning it does not contain any genetic material.

4. Nucleus and DNA insertion: The nucleus from sheep #1, containing its complete DNA, is inserted into the egg of sheep #4. Essentially, the DNA from sheep #1 is placed inside the Egg of sheep #4.

5. Stimulation and development: The manipulated egg, now containing the DNA from sheep #1, is stimulated to grow and develop. It starts dividing and forming a diploid cell mass, which is a collection of cells containing a complete set of chromosomes.

6. Uterus implantation: The resulting diploid cell mass is then inserted into the uterus of sheep #9, in which it develops further.

7. Birth of Dolly: Finally, sheep #9 gives birth, and the newborn sheep is named Dolly.

Now, to determine which sheep Dolly is a clone of, we need to consider the genetic material involved in the cloning process. Since the nucleus from sheep #1 was inserted into the egg of sheep #4, and sheep #1's DNA is used in the development of Dolly, she is a clone of sheep #1. The genetic material from sheep #1 directs the formation and characteristics of Dolly, making her an exact genetic replica of sheep #1. Therefore, Dolly is not a clone of sheep #4 or sheep #9, but of sheep #1.
