It has been known to withstand radiation levels of up to 1,000 times that which would kill a normal human, living up to its latin name, "strange little berry that withstands radiation." Who knows? It is able to cope without air, water and food, and can withstand very high doses of radiation which would kill a human. The extremophilic bacterium Deinococcus radiodurans is well known for Talking about the cell structure of the organism, its cell envelope consists of at least six layers. “For instance, Deinococcus radiodurans lacks the major repair pathway for double strand breaks that exists in E. coli. Well, the microbe is almost indestructible, bearing the capability of surviving at the surface of Mars which is bombarded with intense radiation.  It can also survive the drought conditions and lack of nutrients. Deinococcus radiodurans Description and significance Deinococcus radiodurans is a red-pigmented, non-motile, spherical bacterium that is 1-2 µm in size. into Deinococcus radiodurans genome (strain R1- ATCC BAA-816) which is responsible for degradation. These places are real chills! Scientific Mystery presents information from the world of science fiction and the famous mysteries. You’ve made my day! The bacterium can even bear the extreme cold. The innermost layer is the plasma membrane. The genome of Deinococcus radiodurans has been sequenced.  The studies have proved that the bacterium contains a protein known as RecA which is essential for radiation resistance. In humans, the oxidative modification of cellular macromolecules by ROS is the basis of various degenerative diseases, cancer, and aging [5,6]. Well, nothing happened to the bacteria, making the researches to estimate that it would 1.2 million years under the Martian conditions to shrink a population of the bacteria to a millionth of its original size. Deinococcus radiodurans – it is a name present in the “Guinness Book of World Record” for being “the world’s toughest…. Now, that you know that with such a complex name, there is a bacterium, you might be wondering how tough it is actually. It also deals in various other interesting topics from the fields as diverse as the human lifestyle to animals’ lives. The high ionizing radiation does shatter the organism’s genome, but it has the ability to stitch its fragments back together. 2009a,b). though Deinococcus radiodurans has not been known to cause death or disease in humans, many humans are very skeptical of releasing microbes into the soil. Rain on other planets isn’t watery; it even rain diamonds on some planets, North Sentinel Island is home to dangerous stone age tribe. Your email address will not be published. "D. radiodurans has taught us -- if you want to survive radiation: protect your proteins," explained study co-author Dr. Michael Daly, professor of Pathology at … Brazilian Wandering Spider can be deadly to humans; beware it!
