variation Flashcards
1
Q
genome sequencing
A
determines entire base sequence of an organisms DNA - allowing it to be compared to other organisms to see how similar they are
2
Q
more modern methods of comparing species
A
- genome sequencing
- amino acid sequencing
- immunological comparisons
3
Q
how do Archea differ from bacteria
A
- genes and protein synthesis more similar to eukaryotes
- membranes contain fatty acids joined to glycerol by ester linkages
- no murein in cell walls
- more complex form of RNA polymerase
4
Q
order of hierarchy
A
taxa domain kingdom phylum class order family genus species
5
Q
binomial name consists of…
A
Genus species
6
Q
artificial classification
A
divides organisms according to differences useful at the time - eg. colour, size, no. of legs
7
Q
phylogenetic classification system
A
arranges species into groups based of the evolutionary origins + relationships – smaller groups placed within larger ones with no overlap
- each group = taxon
8
Q
hierachy
A
- system with groups within groups
- no overlap between them
- order of decreasing size
