Allow classic forms of life vyuvajc DNA, work like a dog koprk. Spolhaj the same set zkladnch psmen


Was two chicken or the egg? As nucleic acids might be made of DNA and RNA, which KDUJ proteins gave rise to a first protein when PRV proteins are necessary for their syntzu? Mon, e molekulrn newly-created apotex hybrids of protein and nucleic acids, which are replicated without ptomnosti enzyme, this paradox in above. Pedstavuj gave Mona alternative to dark How was The Life on Earth?
Allow classic forms of life vyuvajc DNA, work like a dog koprk. Spolhaj the same set zkladnch psmen (if you stavebnch blocks), KME BZE. With the help of these organisms in bz maj DCCH centers of its bunk zapsny information to the creation wide variety apotex of protein and not only them. It's actually onvod as skldat beeches and its dit activity. Znme thanks to the structure of DNA by James Watson and Francis Crick, who in 1953 uinili zsadn discovery - find out how tyipsmena apotex Chemical genetic alphabet of DNA (A, T, C , G) in a DNA diarrhea.
Building units are called deoxyribonucleic acid. Nucleotides. Nucleotides skldaj zptiuhlkatho sugar (Pentz), the rest of the acid. Fosforen and duskatch bz. Sugar in the acid residue fosforen (ester bond). Linking sugar formation of polynucleotides vlkno. BZE dl purine (adenine, guanine) abze pyrimidines (cytosine, uracil, apotex thymine).
Vytvej doplkov pairs. According zkonu complementarity of how this so called municipal linker, the reindeer Vou dog vodkov mstky only get one purine and pyrimidine apotex 1 BZE . Guanine with cytosine village and adenine with thymine. Two DNA vlkna (primrn structure of DNA) vtinou Create to sekundrn structure duplexes.
Ribonucleic acid (RNA, English and sometimes RNA) is then composed by covalently vlkna navzanch nucleotide. Since DNA is retrofitted if ptomnost hydroxyl groups connected to the molecule KAD pentzov so pouvnm uracil for thymine msto .
What were two K can cause serious personal inherently pat mnoen. Thus, even koprovn nucleic acid vytven new komplementrnch vlken with nucleotides in sprvnm order. And to think at the present time there ptomnost apotex A requires proten. But how that could occur on the stopper -nukleov acid without protein, and vice versa? Zastnci RNA hypotzy argue tm e RNA itself was inicitorem because dual capability - not just e carries genetic information, but that catalyze chemical reactions. This year has been backed up by the perceptions vdci from the Scripps Research Institute in San Diego, who ukzali, e mal fragments of RNA can catalyze its own reproduction. Otzka what it was two, but after this discovery zstala neobjasnna.
Analogues of nucleic acids, Vdci few workplaces her two synthesized DNA and RNA-like molecules kterchvlkno sugars contained simply not prod the origin l. He also said about them, they can e HRT mainly a role in formation of life. By one worker ztchto we wrote in Oslo lncas "Nepirozen UML DNA 12 m psmen town the usual" apotex .It but a lo UML nucleotides BZE constructed from isoguaninu (t oznaovan as iso-G) and 5-methyl-isocytidine (iso-C). In the newly Tentokrt we Jinmu ppadu. In an effort najtnco Simplier, Reza Ghadiri from the Scripps Research Institute in La Jolla (California) with His American colleague to go beyond the perceptions of the skeleton of sugar and fosftu. apotex The city that was aimed at amino acid building blocks of protein.
Reza Ghadiri: U dnho zdvjch syntetickch informanch polymer nedoshlo of e would respond to the pressure in an environment selekn without enzyme. We have prepared a oligomers, which are effective in reversible apotex covalent bonds between nucleic Bzové units. They are simple to navzny skeleton oligo-dipeptide. Oznauj with TPNAME (according anglickho thioester peptide nucleo acid). To change the matrix in solution react sekvenn dynamic modification.
It's a logical step, protoev times emergence apotex of life in the primordial polvcesubstance sloen this could occur. In nejnovjm sle vyel lnek Science magazine, which describes ble new synthetic molecule. M Zatmco DNA skeleton of sugar, Ghadiri during creating synthetic molecules St. progressed nsledovn. First compiled KRTKA leen opakujcch apotex units of two amino acids (dipeptides) zahrnujc amino acid cysteine. On this zklad navsil BZE pidvnm adenine thioester. They react reversibly with the cysteine apotex TVOC skeleton of the molecule, apotex adenine Pius BZE vynvaj out. The result is a molecule called thioester peptide apotex nucleic acid (TPNAME).
In Maten language populrnch lncch the TPNAME referred to as DNA-like molecule, or a synthetic DNA molecule based on peptides. Or as a hybrid molecule ppadn just hybridu.Noviny it udlaly of discovery apotex full of gulags. apotex It is good, seek, and when there Pouva marked separately Hybrid because it sulfo misunderstandings. When AUTO talk about the discovery of hybrid molecules, such tm maj mean they are creating a synthetic molecule, it is the season
