Document Summary
Stromatolites fossilized microbial mats consisting of layers of filamentous prokaryotes and trapped sediment. The earth"s environment shifted from anoxic to oxic. An oxygenic phototrophic cyanobacteria: provide support for the mitochondria and chloroplasts having bacterial origins. Mitochondria and chloroplasts: have their own genomes, contain their own ribosomes, 70s like prokaryotes, antibiotics are effective rrna sequences are similar to prokaryotic rrna. Yes: general physiology, detailed physiology conclusion. Percent of guanine plus cytosine in an organisms dna: higher gc content is related to higher tm (temperature at the midpoint of, what is the principle behind dna:dna hybridization? denaturation) Sequence comparison of several housekeeping genes by isolating 6-7 target genes from dna and amplifying them. Yes different organisms contain different fatty acid composition: list the taxonomic hierarchy. Formal recognition of a new prokaryotic species requires: deposition of a sample of the organism in 2 international culture collections (atcc- american type culture collection, official publication of the new species name and description in international.
