Cloning
Overview
Cloning in biology is the process of producing similar populations of genetically identical individuals that occurs in nature when organisms such as bacteria
, insect
s or plant
s reproduce asexually
. Cloning in biotechnology
refers to processes used to create copies of DNA
fragments (molecular cloning
), cells
(cell cloning), or organisms. The term also refers to the production of multiple copies of a product such as digital media
or software.
The term clone is derived from the Ancient Greek
word κλών (klōn, “twig”), referring to the process whereby a new plant can be created from a twig.

Plant
Plants are living organisms belonging to the kingdom Plantae. Precise definitions of the kingdom vary, but as the term is used here, plants include familiar organisms such as trees, flowers, herbs, bushes, grasses, vines, ferns, mosses, and green algae. The group is also called green plants or...
s reproduce asexually
Asexual reproduction
Asexual reproduction is a mode of reproduction by which offspring arise from a single parent, and inherit the genes of that parent only, it is reproduction which does not involve meiosis, ploidy reduction, or fertilization. A more stringent definition is agamogenesis which is reproduction without...

DNA
Deoxyribonucleic acid is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms . The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in...

Cell (biology)
The cell is the basic structural and functional unit of all known living organisms. It is the smallest unit of life that is classified as a living thing, and is often called the building block of life. The Alberts text discusses how the "cellular building blocks" move to shape developing embryos....
