Nucleosides, oo ah dhismooyinka asiidhyada nucleic-ka ah (DNA iyo RNA), waxay door muhiim ah ka ciyaaraan kaydinta macluumaadka hiddaha iyo gudbinta. Halka nukleosides-yada caadiga ah-adenine, guanine, cytosine, thymine, iyo uracil- ay si fiican u yaqaanaan, waa nukleosides-ka la bedelay oo inta badan ku dara lakabka kakanaanta iyo shaqeynta hababka noolaha.
Maxay yihiin Nucleosides la beddelay?
Nucleosides wax laga beddelay waa nucleotides kuwaas oo lagu sameeyay isbeddel kiimiko ah saldhigooda, sonkorta, ama kooxda fosfatka. Wax-ka-beddeladani waxay bedeli karaan sifooyinka jidheed iyo kiimikaad ee nucleotide, oo saameeya isdhexgalka ay la leeyihiin molecules kale oo saameeya qaabka iyo shaqada nucleic acid.
Noocyada Wax ka beddelka iyo Shaqooyinkooda
Wax ka beddelka saldhigga: Kuwani waxay ku lug leeyihiin isbeddelada saldhigga nitrogenous ee nucleotide. Tusaalooyinka waxaa ka mid ah methylation, acetylation, iyo glycosylation. Wax ka beddelka salka ayaa saameyn kara:
Xasilooni: Saldhigyada wax laga beddelay waxay kordhin karaan xasilloonida asiidhyada nucleic-ka, iyaga oo ka ilaalinaya hoos u dhaca.
Aqoonsiga: Saldhigyada la beddeley waxay u adeegi karaan sidii goobo lagu aqoonsan karo borotiinnada, saameynaya hababka sida kala qaybinta RNA iyo isku-darka borotiinka.
Shaqada: Saldhigyada la beddelay ayaa beddeli kara shaqada asiidhyada nucleic-ka, sida lagu arkay tRNA iyo rRNA.
Wax ka beddelka Sonkorta: Wax ka beddelka sonkorta ribose ama deoxyribose waxay saameyn kartaa is-waafajinta iyo xasilloonida aashitada nucleic. Wax ka beddelka sonkorta caadiga ah waxaa ka mid ah methylation iyo pseudouridylation.
Beddelka Fosfate-ka: Isbeddellada lagu sameeyo laf-dhabarka fosfattu waxay saameyn ku yeelan karaan xasilloonida iyo dabacsanaanta acid nucleic. Methylation ee kooxaha phosphate waa wax ka beddel caadi ah.
Doorarka Nucleosides La Beddelay ee Nidaamyada Nafleyda
Xasiloonida RNA: Nucleosides-ka la beddelay waxay gacan ka geystaan xasilloonida unugyada RNA, iyaga oo ka ilaalinaya hoos u dhaca.
Protein Synthesis: Nucleosides la beddelay ee tRNA waxay door muhiim ah ka ciyaaraan isku-dhafka borotiinka iyagoo saameeya isdhexgalka codon-anticodon.
Xeerka Hiddaha: Wax ka beddelka DNA-ga iyo RNA waxa ay nidaamin karaan muujinta hidda-wadaha iyada oo saamaynaysa qoraalka, kala-guurka, iyo tarjumaada.
Ku-noqoshada Fayraska: Fayrasyo badan ayaa wax ka beddela asiidhkooda nucleic-ka ah si ay uga baxsadaan habka difaaca ee martida loo yahay.
Cudur: Isbeddellada qaababka nucleoside ee la beddelay ayaa lala xiriiriyay cudurro kala duwan, oo uu ku jiro kansar.
