Enzyme

... region widely dispersed, instead tending to keep the amino acids involved in each active region compacted fairly closely together in the chain and conserved against mutation, separating these regions by long stretches of 'spacer' amino acids where mutation is much less critical (although some mutations in ...

Genomics

... biological discoveries. If a particular DNA sequence or pattern is present among many members of a clade , that sequence is said to have been conserved among the species. Evolutionary conservation of a DNA sequence may imply that it confers a relative selective advantage to the organisms that ...

Insulin

... to human insulin (2 amino acid difference for bovine insulin, 1 amino acid difference for porcine). Insulin is a protein which has been very strongly conserved across evolutionary time. Differences in suitability of beef, pork, or fish insulin preparations for particular patients have been primarily the ...

Intron

... of a gene. Intron evolution There are two competing theories as to the evolutionary origin of introns, which is usually studied in a highly conserved family of genes such as the actins . In the introns-early model ancestral genes are believed to have included a large number of introns, some of ...

Neutral theory of molecular evolution

... been argued, is predictable from the error rate of the enzymes that carry out DNA replication --enzymes that have been well studied and are highly conserved across all species. Thus, the neutral theory is the foundation of the molecular clock technique, which evolutionary molecular biologists use to ...
