Document Summary

Hadeon to proterozoic is the final information for the second midterm. Looking at the organization of the world into three domains archaea, eubacteria and eukarya. The central dogma of biology replication, transcription and translation. Dna replication, translation of message: monera interrupting gene sequences, gene itself (nucleotides sequences did not code: they are called introns) No histones stabilizing the dna in eubacteria. Primary protein sequence between the two groups is different, in archaea using methionine and the eubacteria using formymethione. They should be divided into two simple groups. Eukaryote cell was then developed and belonged in their own domain. There is a huge amount of genetic variation: luca: last universal common ancestor. Will either evolve into the bacterial lineage or into the eukaryote lineage of organisms. Archaea closely related to the eukaryote (a sister group: they are not the founding of the first forms of bacteria that occurred on the planet. Shape: cocci (circular) , bacilli (rod-like), spirillai, and square.
