What Is Cloning?

What Is Cloning?

Scientists can produce genetically identical copies of genes, cells, and tissues. They can also clone entire organisms, such as deer, sheep, and monkeys. (From NIH’s NHGRI)

From the US National Institutes of Health (NIH) fact sheet (https://www.genome.gov/25020028/cloning-fact-sheet/)
The fact sheet includes links to the following areas

 

For example

What is cloning?

The term cloning describes a number of different processes that can be used to produce genetically identical copies of a biological entity. The copied material, which has the same genetic makeup as the original, is referred to as a clone.

Researchers have cloned a wide range of biological materials, including genes, cells, tissues and even entire organisms, such as a sheep.

Do clones ever occur naturally?

Yes. In nature, some plants and single-celled organisms, such as bacteria, produce genetically identical offspring through a process called asexual reproduction. In asexual reproduction, a new individual is generated from a copy of a single cell from the parent organism.

Natural clones, also known as identical twins, occur in humans and other mammals. These twins are produced when a fertilized egg splits, creating two or more embryos that carry almost identical DNA. Identical twins have nearly the same genetic makeup as each other, but they are genetically different from either parent.
