21Codon — A set of any three adjacent bases in the DNA or RNA. There are 64 different codons of which 61 specify the incorporation of an amino acid into a polypeptide chain while the remaining three are stop codons that signal the end of a polypeptide. For …
22Living polymerization — In polymer chemistry, living polymerization is a form of addition polymerization where the ability of a growing polymer chain to terminate has been removed Ref|1. This can be accomplished in a variety of ways. Chain termination and chain transfer …
23Radical polymerization — is a type of polymerization in which the reactive center of a polymer chain consists of a radical.The polymerization reaction is initiated by three classes of free radical initiators: * certain compounds that can be broken down in two radicals at …
24chemical reaction — Any chemical process in which substances are changed into different ones, with different properties, as distinct from changing position or form (phase). Chemical reactions involve the rupture or rearrangement of the bonds holding atoms together… …
25Thermal degradation of polymers — is molecular deterioration as a result of overheating. At high temperatures the components of the long chain backbone of the polymer can begin to separate (molecular scission) and react with one another to change the properties of the polymer.… …
26Shotgun sequencing — In genetics, shotgun sequencing, also known as shotgun cloning, is a method used for sequencing long DNA strands. It is named by analogy with the rapidly expanding, quasi random firing pattern of a shotgun.Since the chain termination method of… …
27Stop codon — In the genetic code, a stop codon (or termination codon) is a nucleotide triplet within messenger RNA that signals a termination of translation.[1] Proteins are based on polypeptides, which are unique sequences of amino acids. Most codons in… …
28Ziegler-Natta catalyst — A Ziegler Natta catalyst is a reagent or a mixture of reagents used in the production of polymers of 1 alkenes (α olefins). Ziegler Natta catalysts are typically based on titanium compounds and organometallic aluminium compounds, for example… …
29Polymerization — An example of alkene polymerization, in which each Styrene monomer unit s double bond reforms as a single bond with another styrene monomer and forms polystyrene. In polymer chemistry, polymerization is a process of reacting monomer molecules… …
