Essay / Research Paper Abstract
This 4 page paper provides an overview of the current literature on this topic. Current scientific research still shows a significant debate over the origins of eukaryotic flagella. Lynn Margulis first proposed endosymbiont theory in an effort to settle the debate on the origins of structures, including eukaryotic flagella. Her theory and the use of 16s rRNA analysis provided a basis for relating the origins of both mitochondria and chloroplasts, yet does not completely resolve arguments over the origins of the eukaryotic flagella. Bibliography lists 3 sources.

including eukaryotic flagella. Her theory and the use of 16s rRNA analysis provided a basis for relating the origins of both mitochondria and chloroplasts, yet does not completely resolve
arguments over the origins of the eukaryotic flagella. Questions still prevail in the scientific community, including whether eukaryotic cilia and flagella arise from an endosymbiont eubacterium, as proposed by
Margulis. In assessing this question, it is necessary to consider the basis for Margulis theory, and also understand the components of the prokaryotic cystoskeleton that may support the argument
that the eukaryotic flagella arise from an endosymobiont eubacterium. Lynn Margulis endosymbiont theory was developed after the presentation of some very specific outcomes that are considered fact. Margulis
theory is based in the belief that organelle genomes probably began as eubacterial or cyanobacterial endsymbionts (Molecular Genetics, 2003). The following are some of the central facts that were
related in creating a comparative view of the organelle genomes and eubacterial or cyanobacterial endsymbionts: * There is a great similarity between the RNA polymerases of organelles and eubacteria, even
more so than when compared with eucaryotes. Both bacterial and organelle polymerases have the same inhibitors and are insensitive to the inhibitors of eucaryotic RNA polymerases (Molecular Genetics, 2003).
* Protein synthesis follows the same pattern relative to the comparison between organelles and eubacteria and the differentiation from eucaryotic RNA polymerases (Molecular Genetics, 2003). * Existing analysis shows
a common ancestor between modern endosymbiotic bacteria and mitochondrial rDNA (Molecular Genetics, 2003). * " Similarly, 16S rDNA phylogenetic analysis suggests that most plastid rDNA genes shared common ancestors with
a cyanobacterium. Euglena and Chlamydomonas rDNAs probably arose from a different ancestral cyanobacterial rDNA" (Molecular Genetics, 2003). * Comarisons of organelle genomes demonstrate the presence of some species of the
