Isicelo
I-RNA ne-DNA zisetshenziswa njengomuthi.Abantu bathatha inhlanganisela ye-RNA/DNA ukuze bathuthukise inkumbulo nokuba bukhali kwengqondo, belaphe noma bavimbele isifo se-Alzheimer, belaphe ukucindezeleka, bakhulise amandla, baqinise isikhumba, bakhulise umdlandla wobulili, futhi balwe nemiphumela yokuguga.
I-RNA (efushanisiwe ngokuthi i-RNA, i-Ribonucleic Acid) ingumthwali wolwazi lofuzo olutholakala kumangqamuzana aphilayo nakwamanye amagciwane kanye nezinto eziphilayo ezifana negciwane.I-RNA iqukethe ama-ribonucleotides afingqiwe ngamabhondi e-phosphodiester ukuze enze ama-molecule amade afana neketango.I-molecule ye-ribonucleic acid iqukethe i-phosphate, i-ribose nezisekelo.kunezinhlobo ezine eziyinhloko zezisekelo ku-RNA, okungukuthi A (adenine), G (guanine), C (cytosine) kanye no-U (uracil), lapho u-U (uracil) ethatha indawo ka-T (thymine) ku-DNA.Indima ye-RNA emzimbeni iwukuqondisa ukwakheka kwamaprotheni.
Ingqamuzana elilodwa emzimbeni womuntu liqukethe cishe amaphesenti angu-10 e-RNA (equkethe cishe amaphesenti angu-7 e-DNA).Uma iqhathaniswa ne-DNA, i-RNA inezinhlobonhlobo eziningi, isisindo samangqamuzana amancane kanye nokuhlukahluka okukhulu kokuqukethwe.I-RNA ingahlukaniswa ibe yi-RNA yesithunywa kanye ne-RNA engafaki amakhodi ngokuya ngesakhiwo nomsebenzi.I-RNA engakhohlisi ihlukaniswe yaba i-RNA enkulu engafaki amakhodi futhi I-RNA encane engafaki ikhodi.I-RNA enkulu engafaki amakhodi ihlanganisa i-ribosomal RNA, iketango elide i-RNA engafaki ikhodi.I-RNA encane engafaki ikhodi ihlanganisa ukudlulisa i-RNA, i-nuclease, i-molecule encane i-RNA, njll.I-molecule encane i-RNA (20~300nt) ihlanganisa i-miRNA, i-SiRNA, i-piRNA, i-scRNA, i-snRNA, i-snoRNA, njll. Amagciwane aphinde abe ne-molecule encane i-RNA (50~500nt).
I-RNA, njenge-DNA, iphinde ibe iketango le-polynucleotide elakhiwe ngama-nucleotide ahlukahlukene axhunywe amabhondi angu-3′,5′-phosphodiester, kodwa ihluke ku-DNA ngezindlela eziningi.
