The Discovery Of The Dna - 1088 Words

Scientist Who Co-Discovered the DNA Says Our Genes Were Brought Here by Aliens Francis Crick (8 June 1916 — 28 July 2004) was an English scientist who was most noted for being a co-discoverer of the structure of the DNA molecule in 1953 alongside James D. Watson. Francis Crick Watson and Maurice Wilkins were jointly awarded the 1962 Nobel Prize for Physiology for Medicine â€Å"for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material.† He was clearly a brilliant scientist who unfortunately, like many other brilliant minds who came up with theories that challenged the accepted frameworks at the time, wasn’t given much ‘press.’ In his book published in 1982,†¦show more content†¦After all, theories like this aren’t just born out of nowhere and this gentleman won the Nobel Prize for the study of DNA. Thoughts like this should not be taken lightly and evidence should be examined to see if it’s a plausible hypothesis. Please keep in mind while reading this article that, although we’ve discovered much, we have yet to identify the biological functions of large portions of our DNA. There is so much mystery wrapped in what could possibly hold the answer to life itself and the origins of the human race. A few years ago, Chandra Wickramasinghe, the Director of the Buckingham Centre for Astrobiology at the University of Buckingham in the U.K., published a paper regarding their supposed findings of the first-ever evidence of extraterrestrial life found in a celestial body. At the time, Wickramasinghe pointed out to Huffington Post how, in 1962: â€Å"Hoyle and I pioneered the theory of carbon grains in space to replace the old ice grain theory. This was vehemently resisted by the astronomical community at the outset, but with the dawn of infrared spectroscopy, the ice grain theory gave way to the carbon dust theory. â€Å"Over a few years, after a great deal of model-fitting, we came to the conclusion that material similar to biomaterial fitted all the available data in astronomy. We considered the possibility that microbiology had a universal character, and no observations in astronomy or new information from biologyShow MoreRelatedThe Discoveries Of The Discovery Of Dna957 Words   |  4 PagesThe discovery of DNA is arguably one of the most important breakthroughs of genetics in the 19th and 20th centuries. Its discovery is littered with successes, failures, and even heartache. Numerous scientists are attributed to the discovery of DNA as a genetic material and even many more are also credited to the discovery of the molecule, structure, and function. Without the work of these remarkable scientists, the medical advancements over the last 50 years would not be possible.

* Eukaryotic* Unicellular* Microorganisms* Asexual/sexual reproduction* Flagella A ; Cilia with 9+2 microtubules Beginning* The term â€Å"protist† is derived from the Grecian protiston. intending the â€Å"first of all 1s. † * Individual protists tend to be rather little. either unicellular or an uniform multicellular mass. At one point. â€Å"Protista† encompassed everything that wasn’t an animate being or works. until the coming of cellular biological science which noted cardinal differences between bacteriums and the remainder of life. * Now bacteriums are a separate class from protists. Group* Animal-like Protists( Mastigophorans. Sarcodines. Sporozoa. Ciliates ) * Fungus-like Protists( Myxomycota. Acrasiomycota )* Plant-like Protists( Euglenophytes. Chrysophytes. Dinoflagellates ) ANIMAL-LIKE PROTISTSProtists that are classified as animal-like are called protozoons and portion some common traits with animate beings. All animal-like protists are heterotrophs. Likewise. all animal-like protists are able to travel in their environment in order to happen their nutrient. Unlike. animate beings. nevertheless. animal-like protists are all unicellular. SUB-GROUPS:* Mastigophorans – Protists with scourge ; mitotic division * Sarcodines – Protists with pseudopods ; by binary fission ( mitosis ) *Sporozoa – Parasitic protists ; make non travel on their ain * Ciliates – Protists with cilia ; reproduces asexually ( binary fission ) or sexually ( junction ) ECONOMIC IMPORTANCE OF PROTOZOANS1. FoodProtozoa provide nutrient for insect larvae. crustaceans and worms. which are taken by big animate beings like fishes. lobsters. boodles. and pediculosis pubis. which are eaten by adult male. 2. Symbiotic ProtozoaCertain Protozoa like Trichonympha and Colonymphya etc. live in the intestine of white ants which help in the digestion of cellulose. 3. Insect Control Several Protozoas control harmful insects by prevailing their organic structures. 4. Helpful in SanitationA big figure of protozoa life in contaminated H2O provender upon waste organic affairs and therefore sublimate it. 5. Oil ExplorationPetroleum is organic beginning. The skeletal sedimentation of Formmifera and Radiolaria are frequently found in association with oil sedimentations. In this mode they help in the exact location of oil. 6. Scientific Study Many Protozoas are used in biological and medical researches. A Holotricha. Tetrachymena geleiiis used in nutritionary research. The effects of assorted nutrients and toxicants have been investigated on this protozoon. PLANT-LIKE PROTISTSPlant-like protists are autophytic. They can populate in dirt. on the bark of trees. in fresh H2O. and in salt H2O. These protists are really of import to the Earth because they produce a batch of O. and most living things need O to last. Furthermore. these plant-like protists form the base of aquatic nutrient ironss. SUB-GROUPS:* euglenophytes – Unicellular. photosynthetic. individual scourge * chrysophytes – Unicellular. photosynthetic. chlorophyll a and hundred * dinoflagellates – Unicellular. two whirling scourge. chlorophyll a and degree Celsius Economic Importance ( PROTISTA )Protists are really of import in biological and economic point of position. They are utile in the undermentioned manners: * Source of nutrient:Some protests such as kelps are comestible and may be used to get the better of deficit of nutrient in universe. * Source of commercial merchandises:Many marine protests are besides beginning of many utile substances like algin. agar. Irish moss and antiseptics. * Source of medical specialties:Sodium Laminaria sulfate is used as a blood coagulator. Fucoidin and Lipo-Hepin are the algae merchandises. which are besides used as blood coagulators. Lyngbya produces an anticancer compound. * Source of mineral:Kelps are rich in Na. K. iodine etc. They are good beginning of these minerals. * Biological research:Protists are besides used in biological researches e. g. Chlorella is unicellular non-motile green algae. * Primary Producer of Aquatic Ecosystem:Most of the protests are primary manufacturers of the aquatic ecosystem therefore they play a basic function in nutrient ironss. supplying nutrient and O to other beings. * Pathogens: Most of the organisms belongs to this group are infective beings. They cause many diseases in adult male or in veggies and fruits like it do late blight murphies in murphies and causes diseases in some fishes.
