... All present day living beings are thought to have evolved by processes that give rise to key biomolecules through molecular evolution, a series of mutational mechanisms affecting DNA and in turn the proteins encoded by DNA. These new biomolecules confer new or enhanced capabilities, which can give r ...

The neutral theory of molecular evolution Motoo Kimura (1968) High levels of polymorphism (variation) in protein and DNA sequences among individuals and species are difficult to reconcile with mutation-selection equilibrium (Ch 5.4) Most mutations affecting fitness are deleterious, hence quickly eli ...

... The Genome: smaller than we once thought • The collection of all the DNA in the cell is referred to as the genome. • We now know that most of the DNA does not code for amino acid sequences • Non-coding segments guide translation and are called introns • Coding segments are called exons ...

... Rooting trees. Molecular clocks. Are vultures storks? Are whales pigs? and Were Tasmanian wolves opossums? The Tree of Life. Lab: your choice of a gene family to reconstruct phylogeny. 4. Evolution of Genetic code and codon usage. Lab: is the genetic code one in a million? 5. Chromosomal evolution. ...
