The Science of Cloning!

It's controversial!

What is cloning?

Cloning is when two or more organisms are created with exactly the same DNA.

How would you go about cloning an organism?

There are a couple of ways to do this: artificial embryo twinning and somatic cell nuclear transfer.

Method 1: Artificial Embryo Twinning

Artificial embryo twinning is exactly what the name suggests. In nature, the zygote divides in two just after fertilization and creates two individual organisms with the exact same DNA. Artificial embryo twinning is exactly the same, except it occurs in a Petri dish instead of the mother's body and the zygote is manually divided in its early stages so that the two separate embryos grow as individuals. After the zygote is separated, it is placed into the surrogate mother and is carried and delivered as usual.

Method 2: Somatic Nuclear Transfer

Somatic cell nuclear transfer is when a somatic cell(any cell in the body other than sperm/egg) is taken from a donor and its nucleus is transferred to the egg cell in the surrogate mother. Carriage and delivery are the same as usual.

Pros/Cons

Pros

1. It can create more food for the world and help stop the world hunger problem.

2. Can create new organs for the sick.

Cons

1.Scientists can't make perfect clones yet. Most die before birth.

2. Can be considered murder.
