Cloning | Definition, Process, & Types | Britannica
2024年10月1日 · Cloning, the process of generating a genetically identical copy of a cell or an organism. Cloning happens often in nature, as when a cell replicates itself asexually without genetic alteration or recombination.
Cloning - Wikipedia
Cloning is the process of producing individual organisms with identical genomes, either by natural or artificial means. In nature, some organisms produce clones through asexual reproduction; this reproduction of an organism by itself without a mate is known as parthenogenesis.
Cloning Fact Sheet - National Human Genome Research Institute
2020年8月15日 · 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.
What is Cloning - University of Utah
What is Cloning. Clones are organisms that are exact genetic copies. Every single bit of their DNA is identical. Clones can happen naturally—identical twins are just one of many examples. Or they can be made in the lab.

2021年11月17日 · The most basic definition of cloning is the creation of an exact genetic copy of an organism, tissue, cell or gene, according to the U.S. National Library of Medicine. The how and why of...
Cloning - National Human Genome Research Institute
3 天之前 · Cloning, as it relates to genetics and genomics, involves using scientific methods to make identical, or virtually identical, copies of an organism, cell or DNA sequence. The phrase “molecular cloning” typically refers to isolating and copying a particular DNA segment of interest for further study.
Traditional Cloning Basics | Thermo Fisher Scientific - US
Traditional Cloning Basics. Traditional cloning relies on recombinant DNA methods that begin with preparing a vector to receive an insert DNA by digesting each with restriction enzymes.

Cloning - National Geographic Society
2024年10月1日 · Cloning is a technique scientists use to make exact genetic copies of living things. Genes, cells, tissues, and even whole animals can all be cloned. Some clones already exist in nature. Single-celled organisms like bacteria make exact copies of themselves each time they reproduce. In humans, identical twins are similar to clones.
