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]
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
A multiple cloning site ( MCS ), also called a polylinker, is a short segment of DNA which contains many (up to ~20) restriction sites - a standard feature of engineered plasmids. [ 1] Restriction sites within an MCS are typically unique, occurring only once within a given plasmid. The purpose of an MCS in a plasmid is to allow a piece of DNA ...
Restriction site. Restriction sites, or restriction recognition sites, are located on a DNA molecule containing specific (4-8 base pairs in length [ 1]) sequences of nucleotides, which are recognized by restriction enzymes. These are generally palindromic sequences [ 2] (because restriction enzymes usually bind as homodimers ), and a particular ...
DNA binding sites are a type of binding site found in DNA where other molecules may bind. DNA binding sites are distinct from other binding sites in that (1) they are part of a DNA sequence (e.g. a genome) and (2) they are bound by DNA-binding proteins. DNA binding sites are often associated with specialized proteins known as transcription ...
The branch of biology that studies biological activity at the molecular level, in particular the various mechanisms underlying the biological processes that occur in and between cells, including the structures, properties, synthesis, and modification of biomolecules such as proteins and nucleic acids, their interactions with the chemical ...
Segregating site. Segregating sites are positions which show differences ( polymorphisms) between related genes in a sequence alignment (are not conserved ). [1] Segregating sites include conservative, semi-conservative and non-conservative mutations. The proportion of segregating sites within a gene is an important statistic in population ...
In biology and biochemistry, the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction. The active site consists of amino acid residues that form temporary bonds with the substrate, the binding site , and residues that catalyse a reaction of that substrate, the catalytic site .
