Nucleosides, ihe mgbochi ụlọ nke nucleic acid (DNA na RNA), na-arụ ọrụ dị mkpa na nchekwa na mbufe ozi mkpụrụ ndụ ihe nketa. Ọ bụ ezie na ọkọlọtọ nucleosides-adenine, guanine, cytosine, thymine, na uracil-bụ ndị a maara nke ọma, ọ bụ nucleosides ndị a gbanwere na-agbakwụnyekarị ihe mgbagwoju anya na ịrụ ọrụ na usoro ndu.
Kedu ihe bụ Nucleosides gbanwere?
Nucleosides emezigharịrị bụ nucleotides bụ ndị megharịrị kemịkalụ mgbanwe na ntọala ha, shuga, ma ọ bụ phosphate. Mgbanwe ndị a nwere ike ịgbanwe ọdịdị anụ ahụ na kemịkal nke nucleotide, na-emetụta mmekọrịta ya na ụmụ irighiri ihe ndị ọzọ ma na-emetụta nhazi na ọrụ nke nucleic acid.
Ụdị mgbanwe na ọrụ ha
Mgbanwe ntọala: Ndị a gụnyere mgbanwe na ntọala nitrogen nke nucleotide. Ọmụmaatụ gụnyere methylation, acetylation, na glycosylation. Mgbanwe ntọala nwere ike imetụta:
Nkwụsi ike: ntọala ndị gbanwere nwere ike ime ka nkwụsi ike nke acid nucleic dịkwuo elu, na-echebe ha pụọ na mmebi.
Nkwenye: Ntọala gbanwetụrụ nwere ike bụrụ saịtị amata maka protein, na-emetụta usoro dị ka RNA splicing na protein njikọ.
Ọrụ: Ntọala ndị gbanwere nwere ike gbanwee ọrụ nke acid nucleic, dị ka a hụrụ na tRNA na rRNA.
Mgbanwe Sugar: Mgbanwe na ribose ma ọ bụ shuga deoxyribose nwere ike imetụta nhazi na nkwụsi ike nke acid nucleic. Mgbanwe shuga a na-ahụkarị gụnyere methylation na pseudouridylation.
Mgbanwe nke Phosphate: Mgbanwe na ọkpụkpụ azụ phosphate nwere ike imetụta nkwụsi ike na mgbanwe nke nucleic acid. Methylation nke otu phosphate bụ mgbanwe a na-ahụkarị.
Ọrụ nke Nucleosides gbanwetụrụ na Sistemụ Ngwọta
Nkwụsi ike RNA: Nucleosides gbanwere na-enye aka na nkwụsi ike nke mkpụrụ ndụ RNA, na-echebe ha pụọ na mmebi.
Njikọta Protein: Nucleosides gbanwere na tRNA na-arụ ọrụ dị mkpa na njikọ protein site na imetụta mmekọrịta codon-anticodon.
Iwu Gene: Mgbanwe na DNA na RNA nwere ike ịhazi okwu mkpụrụ ndụ ihe nketa site n'imetuta ederede, nbido, na ntụgharị asụsụ.
Mmụgharị Viral: Ọtụtụ nje na-agbanwe acid nucleic ha iji gbanahụ usoro ahụ ji alụso ọrịa ọgụ.
Ọrịa: Mgbanwe n'ụdị nucleoside agbanweela na ọrịa dị iche iche, gụnyere ọrịa kansa.
Ngwa nke Nucleosides gbanwere
Ndị na-agwọ ọrịa: A na-eji nucleosides gbanwetụrụ na mmepe nke ọgwụ nje na-egbochi ọrịa cancer.
Biomarkers: Nucleosides gbanwere nwere ike ije ozi dị ka ihe na-ahụ maka ọrịa, na-enye nghọta n'ime usoro ọrịa.
Usoro ihe ọmụmụ sịntetik: A na-eji nucleosides gbanwetụrụ iji mepụta acid nucleic sịntetị nwere ihe ọhụrụ.
Nanotechnology: Enwere ike iji nucleosides gbanwee iji wuo nanostructures maka ngwa dị iche iche.
Mmechi
Nucleosides emezigharịrị bụ akụkụ dị mkpa nke sistemu ndu, na-arụ ọrụ dị iche iche na mkpụrụ ndụ ihe nketa, ụkpụrụ, na usoro cellular. Ngwongwo ha pụrụ iche emewo ka ha bụrụ ngwaọrụ bara uru na teknụzụ biotechnology, ọgwụ na nanotechnology. Ka nghọta anyị banyere ụmụ irighiri ihe ndị a na-aga n'ihu na-eto eto, anyị nwere ike ịtụ anya ịhụ ọbụna ngwa ọhụrụ ga-apụta.
