• propel
  • In last May's issue of Bioinformatics, he reported that part of ASPM's DNA sequence resembles that of genes involved in the function of flagella, which propel sperm. (gnxp.com)
  • An example of a flagellated bacterium is the ulcer-causing Helicobacter pylori, which uses multiple flagella to propel itself through the mucus lining to reach the stomach epithelium. (wikipedia.org)
  • Behe
  • As with many aspects of science that creationists do not understand, the evolution of the flagellum is always on their "questions science cannot answer" lists, specifically with regards to irreducible complexity as Michael Behe postulates it: How could the flagellum have appeared? (rationalwiki.org)
  • In The Flagellum Unspun Ken Miller recreates the argument he used against Behe in the Dover Courthouse. (rationalwiki.org)
  • Dynein
  • These flagellar complexes then attach to the IFT machinery, which includes the IFT motors (kinesin in orange and dynein in red) and IFT particles (blue), for transport into the flagellum and subsequent assembly into the flagellar structure. (els.net)
  • axoneme
  • In addition, the Chlamydomonas axoneme contains a structure called the 5-6 bridge and B‐tubule projections found in the proximal part of the flagellum on outer doublets 1, 5 and 6. (els.net)
  • sensory
  • At the anterior end is the basal body complex (pink) and the two motile, sensory flagella (red). (els.net)
  • The primary role of the flagellum is locomotion, but it also often has function as a sensory organelle, being sensitive to chemicals and temperatures outside the cell. (wikipedia.org)
  • organelle
  • For example, the bubonic plague bacterium Yersinia pestis has an organelle assembly very similar to a complex flagellum, except that is missing only a few flagellar mechanisms and functions, such as a needle to inject toxins into other cells. (wikipedia.org)
  • Eubacterial flagellum is a multifunctional organelle. (wikipedia.org)
  • mechanism
  • IFT is the mechanism by which flagella are generated, maintained and resorbed. (els.net)
  • Cambridge scientists have uncovered the mechanism by which bacteria build their surface propellers (flagella) - the long extensions that allow them to swim towards food and away from danger. (phys.org)
  • pathway
  • There are three distinct groups of flagella, each of which has its own evolutionary pathway ( convergent evolution ). (rationalwiki.org)
  • We model the chemotactic signaling pathway reactions, couple them to a multi-flagella model for propelling and take the effects of rotational diffusion into account to accurately reproduce the experimental observations of single cell swimming. (springer.com)
  • flagellar
  • I think the evolution of the bacterial flagellum is far too improbable to happen without deliberate fine-tuning of the events that lead up to it, even though most of the flagellar components have precursor homologues. (wordnik.com)
  • argue
  • Intelligent design proponents and creationists argue that the flagellum is so complex that it cannot have evolved on its own - necessitating the intervention of an intelligent designer . (rationalwiki.org)
  • functional
  • Despite the fact that biologist Ken Miller and others have specifically shown exactly how a flagellum could have evolved, as distinct, critical, functional and useful steps, creationists continue to use the flagellum as one of their oft-repeated "self-evident" arguments. (rationalwiki.org)
  • long
  • Euglena gracilis is a tiny, single-celled organism with a long, oval body, tail-like flagella and chloroplasts for producing food energy from sunlight. (reference.com)
  • different
  • Behe's criticism of neo-Darwinian explanations for the evolution of things like the flagellum is essentially no different than Margulis's. (wordnik.com)
