What are anaerobic extremophiles?
Extremophiles are a very special type of organism, which can survive many situations that others could not. An Anaerobe is a type of extremophile that can survive without oxygen.
Can humans be immune to radiation?
Dsup proteins embrace tardigrade DNA and envelope it, protecting it from harm due to radiation, while keeping all of its normal functions intact. Assuming this ability can be successfully recreated in all the cells of a fully-grown organism like us, it could make human beings and other animals immune to radiation.
Which is a class of extremophile?
Extremophiles are animals that live and thrive under extreme environmental conditions. Classes of extremophiles include acidophiles (acid lovers), halophiles (salt lovers), psychrophiles (extreme cold lovers), and radiophiles (radiation lovers).
Where do anaerobic extremophiles live?
Natural environments for anaerobic thermophiles range from terrestrial volcanic sites (including solfatara fields) with temperatures slightly above ambient temperature, to submarine hydrothermal systems (sediments, submarine volcanoes, fumaroles and vents) with temperatures exceeding 300 °C, subterranean sites such as …
Who is most sensitive to radiation?
Amongst the body cells, the most sensitive are spermatogonia and erythroblasts, epidermal stem cells, gastrointestinal stem cells. The least sensitive are nerve cells and muscle fibers.
Which is an example of an extremophile organism?
The term extremophiles applies to organisms including microbes, plants and animals, which can sustain life in the extreme environmental conditions such as hot springs, volcanic areas, the deep sea, extreme high and low temperature (>45; <15°C), pressure, oxygen scarcity and a variety of radiations ( Mesbah and Wiegel 2008; Kumar et al. 2010 ).
Which is an example of a radioresistant organism?
A radioresistant organism is an organism that can live in environments with extremely high levels of ionizing radiation. Ionizing radiation is emitted by unstable atoms. These unstable atoms attempt to stabilize by giving off excess energy.
How does radiation affect the DNA of an extremophile?
Transcript of Radio Resistant Extremophiles. Radiation damages DNA and causes mutations. It can do so when the radiation energy is exposed to an organism’s cells. The radiation can cause mutations in the DNA by causing the removal of a nucleotide (therefore sometimes causing incorrect bonds), breaking bonds, and ripping the strand.
Which is the best example of induced radioresistance?
Induced Radioresistance. Though the most radioresistant organisms are microbes, radioresistance is suprisingly high in many organisms, contrary to earlier belief. An example of this is the survival of many animal and plant species around Chernobyl, the site of the infamous nuclear accident.
