Subfunctionalization is a neutral mutation process in which each paralog retains a subset of its original ancestral function. The figure illustrates that the ancestral gene (orange & blue) is capable of both functions before gene duplication. After gene duplication the functional capabilities are divided amongst the gene copies. After this divergence each paralog is capable of independently performing a distinct ancestral function. Subfunctionalization was proposed by Stoltzfus (1999) [1] and Force et al. (1999) [2] as one of the possible outcomes of functional divergence that occurs after a gene duplication event, in which pairs of genes that originate from duplication, or paralogs, take on separate functions. [3] [4] [5] Subfunctionalization is a neutral mutation process; meaning that no new adaptations are formed. [6] [7] During the process of gene duplication paralogs simply undergo a division of labor by retaining different parts (subfunctions) of their original an...

Caenophidia Scientific classification Kingdom: Animalia Phylum: Chordata Class: Reptilia Order: Squamata Suborder: Serpentes Infraorder: Caenophidia The Caenophidia are a derived clade in the suborder Serpentes (snakes), which contains over 80% of all the extant species of snakes. [1] The largest family is Colubridae, but it also includes at least seven other families [1] , at least four of which were once classified as "Colubridae" before molecular phylogenetics helped us understand their relationships. It has been found to be monophyletic. [1] Although the Caenophidia previously was held to exclude Acrochordidae, researchers have recognized that Acrochordids share several traits with the other Caenophidians. [2] Hence Caenophidia is usually considered to comprise Acrochordidae plus more the more derived snakes classified as Colubroidea. Families Superfamily: Acrochordoidea Family: Acrochordidae –file snakes, wart snak...

A tetrapeptide (example: Val-Gly-Ser-Ala) with green highlighted N -terminal α-amino acid (example: L-valine) and blue marked C -terminal α-amino acid (example: L-alanine). The C-terminus (also known as the carboxyl-terminus , carboxy-terminus , C-terminal tail , C-terminal end , or COOH-terminus ) is the end of an amino acid chain (protein or polypeptide), terminated by a free carboxyl group (-COOH). When the protein is translated from messenger RNA, it is created from N-terminus to C-terminus. The convention for writing peptide sequences is to put the C-terminal end on the right and write the sequence from N- to C-terminus.
