Isicelo
I-RNA kunye ne-DNA zisetyenziswa njengamayeza.Abantu bathatha indibaniselwano ye-RNA/DNA ukuphucula inkumbulo kunye nokuba bukhali kwengqondo, ukunyanga okanye ukuthintela isifo sika-Alzheimer, ukunyanga ukudakumba, ukonyusa amandla, ukuqinisa ulusu, ukwandisa inkanuko yesini, nokuchasana nemiphumo yokuguga.
I-RNA (efinyeziweyo njenge-RNA, i-Ribonucleic Acid) ngumthwali wolwazi lofuzo olufumaneka kwiiseli eziphilayo nakwezinye iintsholongwane kunye nezilwanyana ezinjenge-virus.I-molecule ye-ribonucleic acid iqukethe i-phosphate, i-ribose kunye neziseko.kukho iintlobo ezine eziphambili zeziseko kwi-RNA, ezizezi A (adenine), G (guanine), C (cytosine) kunye no-U (uracil), apho i-U (uracil) ithatha indawo ye-T (thymine) kwi-DNA.Indima ye-RNA emzimbeni ikakhulu ukuqondisa ukwakheka kweeproteni.
Iseli enye emzimbeni womntu iqulethe malunga ne-10 pg ye-RNA (equlethe malunga ne-7 pg ye-DNA).Xa kuthelekiswa ne-DNA, i-RNA inoluhlu olubanzi, ubunzima obuncinane be-molecular kunye nokwahluka okukhulu kumxholo.I-RNA inokwahlulwa ibe yi-RNA yesithunywa kunye ne-RNA engekho-coding ngokwesakhiwo kunye nomsebenzi.I-RNA engabonakaliyo ihlulwe ibe yi-RNA enkulu engekho ikhowudi kwaye i-non-coding encinci ye-RNA.I-RNA enkulu engabonakaliyo ibandakanya i-ribosomal RNA, i-chain chain non-coding RNA.I-RNA encinci ye-coding iquka ukudluliselwa kwe-RNA, i-nuclease, i-molecule encinci ye-RNA, njl.I-molecule encinci ye-RNA (20 ~ 300nt) iquka i-miRNA, i-SiRNA, i-piRNA, i-scRNA, i-snRNA, i-snoRNA, njl.
I-RNA, njenge-DNA, nayo ikhonkco ye-polynucleotide eyenziwe ngee-nucleotides ezahlukeneyo ezidityaniswe yi-3',5'-phosphodiester bond, kodwa ihluke kwi-DNA ngeendlela ezininzi.
