BI110 Lecture Notes - Lecture 3: Eukaryote, Succinic Acid, Archaea
Document Summary
Variation within a pop"n of organisms hat can be inherited. Some variants are better able to grow & reprod (higher fitness) in a particular enviro, natural selection. Organisms with the highest fitness will contribute disproportionately to the next gen, leading to a change in pop"n over time. Mutations that harm growth and reprod die out. Mutations that are neither beneficial or harmful persist. Beneficial mutations gradually become incorporated into the genetic makeup of every individual in the species. * you cannot change an individuals genetic material through their life, can only happen thru mutations. 3 diff domains of life; bacteria, archaea & eukaryotes. Bacteria & archaea lack a nucleus, and are therefore prokaryotes. Although bacteria and archaea have a similar cellular structures, eukarya and archaea are more closely related. Differences in individual dna, leading to differences in that individuals rna and proteins. * same dna in all types of cells (ex.
