Xenobiology (XB) is a subfield of synthetic biology, the study of synthesizing and manipulating biological devices and systems. [1] The name "xenobiology" derives from the Greek word xenos, which means "stranger, alien". Xenobiology is a form of biology that is not (yet) familiar to science and is not found in nature. [2]
Nucleic acids may not be the only biomolecules in the universe capable of coding for life processes. [1]Astrobiology (also xenology or exobiology) is a scientific field within the life and environmental sciences that studies the origins, early evolution, distribution, and future of life in the universe by investigating its deterministic conditions and contingent events. [2]
Advances in synthetic biology, like synthesizing viruses since 2002, partially synthetic bacteria in 2010, and synthetic ribosomes in 2013, may lead to the possibility of fully synthesizing a living cell from small molecules, which could enable synthesizing mirror cells from mirrored versions (enantiomers) of life's building-block molecules.
Glycol nucleic acid (left) is an example of a xeno nucleic acid because it has a different backbone than DNA (right).. Xenonucleic acids (XNA) are synthetic nucleic acid analogues that are made up of non-natural components such as alternative nucleosides, sugars, or backbones.

Synthetic biology (SynBio) is a multidisciplinary field of science that focuses on living systems and organisms, and it applies engineering principles to develop new biological parts, devices, and systems or to redesign existing systems found in nature.
The Science of Extraterrestrial Life) is a 2002 popular science book about xenobiology by biologist Jack Cohen and mathematician Ian Stewart. [1] [2] [3] The concept for the book originated with a lecture that Cohen had revised over many years, which he called POLOOP, for "Possibility of Life on Other Planets". [4]
Systems biology is the computational and mathematical analysis and modeling of complex biological systems.It is a biology-based interdisciplinary field of study that focuses on complex interactions within biological systems, using a holistic approach (holism instead of the more traditional reductionism) to biological research.
