Document Summary
Concept 27. 1: structural and functional adaptations contribute to prokaryotic success: describe the structure and function of each of the following prokaryotic features: Concept 27. 2: rapid reproduction, mutation, and genetic recombination promote genetic diversity in prokaryotes. Probabitlity is one in 10 million: genetic recombination- transformation, transduction, and conjugation can bring together dna from diferent cells. A f factor (fertility) is transferred through the hallow pilus. Is either a plasmid or part of the dna. Also these compunds can be used to make amino acids: describe the specializations for nitrogen fixation in a filamentous colony of the cyanobacterium. Anabaena: the dna of this bacteria has genes for photosynthesis and nitrogen fixation. Since o2 doesn"t allow nitrogen fixation, certain cells called heterocysts are created with thicker cells walls to not allow o2 to eneter to do nitrogen fixation while other cells do photosynthesis. Concept 27. 4: molecular systematics is illuminating prokaryotic phylogeny.
