MICR 271 Test 2 Questions with Correct Answers
What two domains of life are the most closely related?
archaea and eukaryotes
Endosymbioent Hypothesis
the idea that eukaryotes stemed from prokaryotes based on the similarities between bacteria
and the mitochondria
-both have seperate DNA
-a-proteobacteria ( a phylum of gram negative bacteria) is the ancestor of the mitochondria
Archazoan Scenario
proto-mitochondrian generated after the formation of the eukaryotic cell
symbiogensis scenario
proto-mitochondria helped develop the eukaryotic cell
phylogenetic tree of life
- helped find the close relationship between archaea and eukaryotes
- comparisin of rRNA sequences
Phylogenomic Tree of Life
uses entire genomes
The Web of Life
- multiple connections between branches
- recognizes HGT
- HGT is only between bacteria
