The unifying theme of biology.
What is evolution?
Favors the survival of multiple genotypes that produce different phenotypes, diverse environment:
Disruptive selection
Reproduce at different times of the day/year
What is temporal isolation?
Secreted from the cells to evade host defenses and hold colony together
What is mucilage?
The use of technology to record, store, and analyze biological information; highly interdisciplinary
What is Bioinformatics?
Population reduced dramatically then rebuilds.
Bottleneck
Each species occupies an ecological niche – the unique set of habitat resources that a species requires, as well as its influence on the environment and other species
What is ecological species concept
These organisms require oxygen.
What are obligate aerobes?
Extranuclear DNA is found in the ___________ & ____________ of eukaryotic genomes.
Mitochondria & Chloroplasts
Naturally found only in a particular location.
What is endemic?
Division of a species into two or more species
What is cladogenesis
Group of species, taxon, consisting of the most recent common ancestor and all of its ancestors
What is a monophyletic group or clade?
Contain DNA from 2 or more sources
Recombinant DNA
Transposable elements contain a central region that encodes for __________________, which is an enzyme that facilitates _______________.
Transposase, transposition
Study of the geographical distribution of extinct and modern species.
What is biogeography?
Hybrids are viable and fertile but following generations have genetic abnormalities:
What is hybrid breakdown?
Which domains are prokaryotic?
What is bacteria and archaea
Which is larger, proteomes or genomes? Why?
Proteomes; alternative splicing, post-translational covalent modification
Similar phenotypes will mate, leading to more homozygotes.
What is assortive mating?
The tempo is more sporadic and species in equilibrium for long periods and then short rapid bursts of changes
What is punctuated equilibrium?
The highest level of classification is the __________.
What is domain?
