The GeneEd website is scheduled to be retired on March 31, 2019. Selected GeneEd content will be transferred to Genetics Home Reference, another online resource from the National Library of Medicine.

We’re interested in feedback from regular users of GeneEd as we determine how best to make this transition. Please share your thoughts in a brief survey.



Cloning is the process of making identical copies of an organism, cell, or DNA sequence. Molecular cloning is a process by which scientists amplify a desired DNA sequence. The target sequence is isolated, inserted into another DNA molecule (known as a vector), and introduced into a suitable host cell. Then, each time the host cell divides, it replicates the foreign DNA sequence along with its own DNA. Cloning also can refer to asexual reproduction.
