Neutral theory of molecular evolution

...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 measure how much time has passed since species diverged from a common ancestor. While the mutation rat...

Intron

...n 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 which have been lost over evolutionary time, leading to the different but similar intron patterns in rel...

Insulin

... 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 result of preparation purity and of allergic reactions to assorted non-insulin substances remaining in th...

Genomics

...s 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 possess it. Conservation also suggests that sequence has functional significance. It may be a protein codi...

Enzyme

...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 these regions can also inactivate the product). This has the additional effect of making each region...
