I-Nucleosides, iibhloko zokwakha ze-nucleic acids (i-DNA kunye ne-RNA), zidlala indima ebalulekileyo ekugcineni ulwazi lwemfuzo kunye nokudluliselwa. Nangona i-nucleosides eqhelekileyo-i-adenine, i-guanine, i-cytosine, i-thymine, kunye ne-uracil-zaziwa kakuhle, yi-nucleosides eguquliweyo ehlala idibanisa ukuntsokotha kunye nokusebenza kwiinkqubo zebhayoloji.
Yintoni iiNucleosides eziGuquliweyo?
Ii-nucleosides ezilungisiweyo ziinucleotides eziye zenziwa ukuguqulwa kwemichiza kwisiseko sazo, iswekile, okanye iqela lephosphate. Olu hlengahlengiso lunokutshintsha izinto ezibonakalayo kunye neekhemikhali ze-nucleotide, ezichaphazela ukusebenzisana kwayo nezinye iimolekyuli kunye nokuchaphazela isakhiwo kunye nomsebenzi we-nucleic acid.
Iindidi zoHlengahlengiso kunye neMisebenzi yazo
Ukuguqulwa Kwesiseko: Oku kubandakanya utshintsho kwisiseko senitrogen ye-nucleotide. Imizekelo ibandakanya i-methylation, i-acetylation, kunye ne-glycosylation. Uhlengahlengiso olusisiseko lunokuchaphazela:
Ukuzinza: Iziseko ezilungisiweyo zinokunyusa ukuzinza kwe-nucleic acids, zikhusele ekuthotyweni.
Ukuqaphela: Iziseko ezilungisiweyo zinokusebenza njengeendawo zokuqaphela iiprotheyini, iinkqubo eziphembelela njenge-RNA splicing kunye neprotein synthesis.
Umsebenzi: Iziseko ezilungisiweyo zinokutshintsha umsebenzi we-nucleic acids, njengoko kubonwa kwi-tRNA kunye ne-rRNA.
Ukuguqulwa kweSugar: Ukuguqulwa kwe-ribose okanye i-deoxyribose ishukela kunokuchaphazela ukuhambelana kunye nokuzinza kwe-nucleic acid. Ukuguqulwa kweswekile okuqhelekileyo kubandakanya i-methylation kunye ne-pseudouridylation.
Ukuguqulwa kwePhosphate: Utshintsho kwi-backbone ye-phosphate inokuchaphazela ukuzinza kunye nokuguquguquka kwe-nucleic acid. I-Methylation yamaqela e-phosphate lutshintsho oluqhelekileyo.
Iindima zeeNucleosides eziGuquliweyo kwiiNkqubo zeBhayoloji
Ukuzinza kwe-RNA: I-nucleosides eguqulwayo inegalelo ekuzinzeni kwee-molecule ze-RNA, ezikhusela ekuthotyweni.
Iprotein Synthesis: Ii-nucleosides ezilungisiweyo kwi-tRNA zidlala indima ebalulekileyo kwiprotein synthesis ngokuphembelela ukusebenzisana kwe-codon-anticodon.
Ukulawulwa kweGene: Ukuguqulwa kwe-DNA kunye ne-RNA kunokulawula ukubonakaliswa kofuzo ngokuchaphazela ushicilelo, ukudibanisa, kunye nokuguqulela.
Ukuphindaphindwa kwentsholongwane: Iintsholongwane ezininzi ziguqula i-nucleic acids yazo ukuze ziphephe amajoni omzimba.
Izifo: Utshintsho kwiipatheni ze-nucleoside ezilungisiweyo ziye zadibaniswa nezifo ezahlukahlukeneyo, kuquka umhlaza.
Ukusetyenziswa kweeNucleosides eziGuquliweyo
Ii-Agents zonyango: Ii-nucleosides ezilungisiweyo zisetyenziselwa ukuphuhliswa kwamachiza e-antiviral kunye ne-anti-cancer.
I-Biomarkers: Ii-nucleosides ezilungisiweyo zinokusebenza njenge-biomarkers zezifo, zibonelela ngengqiqo kwiindlela zokugula.
I-Synthetic Biology: Ii-nucleosides ezilungisiweyo zisetyenziselwa ukudala ii-nucleic acids zokwenziwa ezineempawu zenoveli.
I-Nanotechnology: Ii-nucleosides ezilungisiweyo zingasetyenziselwa ukwakha i-nanostructures kwizicelo ezahlukeneyo.
Ukuqukumbela
Ii-nucleosides ezilungisiweyo zizinto ezibalulekileyo kwiinkqubo zebhayoloji, zidlala iindima ezahlukeneyo ekubonakalisweni kofuzo, kulawulo, kunye neenkqubo zeselula. Iimpawu zabo ezikhethekileyo zibenze izixhobo ezixabisekileyo kwi-biotechnology, amayeza, kunye ne-nanotechnology. Njengoko ukuqonda kwethu ezi molekyuli kuqhubeka ukukhula, sinokulindela ukubona usetyenziso olungakumbi luvela.
