Waliwo endwadde zonna ez’obuzaale mu maka go? Ka tuyige ddala ku (Autosomal Dominant) ne (Autosomal Recessive)!

Ffenna tusikira ebintu ebimu okuva mu bazadde baffe, nedda? Oluusi langi y’amaaso, langi y’enviiri, obuwanvu... ebintu ng’ebyo. Mu ngeri y’emu, naffe tusobola okusikira endwadde ezimu okuva ku bajjajjaffe. Kino kye tuyita obusika bw'obuzaale . Leero tugenda kwogera ku ngeri bbiri enkulu obuzaale buno gye busikira, nga zino ze `(Autosomal Dominant)` ne `(Autosomal Recessive)`. Wadde nga bino biyinza okuwulikika ng’ebigambo bya ssaayansi ebitonotono, ka tugezeeko okubitegeera mu ngeri ennyangu.

Engeri ki ze tusikira okuva mu bazadde baffe?

Mu ngeri ennyangu, buli ky’ofuna okuva mu bazadde bo kiringa langi y’amaaso go, obutonde bw’enviiri zo, engeri gy’oli omuwanvu. Zino ze tuyita engeri ezisikira . Enkola gye tufunamu engeri zino eyitibwa obusika .

Enkola y’obusika `(Autosomal Dominant)` kye ki?

Eno y’emu ku ngeri engeri z’obuzaale gye ziyisibwa okuva mu bazadde okudda mu baana. Teebereza, singa oba maama oba taata aba n'engeri y'obuzaale ezimu, era n'eyisibwa nga ``Autosomal Dominant'', olwo engeri eyo esobola okuyisibwa eri omwana singa omuzadde omu yekka alina obuzaale obwo obukyusiddwa. Ekikulu buli mwana w'omuzadde alina engeri ya ``Autosomal Dominant'' bwetyo alina emikisa gya 50% (omu ku babiri) okufuna engeri eyo. Ekyo kitegeeza nti omwana ayinza okukifuna oba nedda. Kiba ng’okufuumuula ekinusu. Jjukira nti ebintu ebyo biyisibwa mu baana singa wabaawo enkyukakyuka mu ``Sperm'', ``Egg'', oba ``DNA'' y'abazadde.

Mu ngeri ennyangu: Mu ``Autosomal Dominant'', omwana asikira engeri eyo ng'omuzadde omu yekka asikira obuzaale "obufuga".

Kale nkola ki ey’okusikira `(Autosomal Recessive)`?

Eno y’engeri endala ey’obusika. Naye ono wa njawulo katono. Omuzadde alina engeri ya ``Autosomal Recessive`` tajja kulaga bubonero bwonna. Kwe kugamba, bayinza n’obutamanya nti balina obuzaale. Engeri eyo okusobola okuyisibwa mu baana baabwe, abazadde bombi balina okuba nga basitula obuzaale obukyusiddwa olw’engeri eyo. Singa abazadde bombi batambuza ekika kino eky'obuzaale "obunafu", buli omu ku baana baabwe alina emikisa 25% (omu ku bana) okusikira embeera/engeri y'obuzaale. Ekyo kitegeeza nti omwana ayinza okuba n’embeera eno, oba okuba omutambuze w’obuzaale, oba okuba omulamu obulungi ddala. Wano ne bino biyisibwa mu baana singa wabaawo enkyukakyuka mu ``Sperm``, ``Egg`` oba ``DNA``.

Mu ngeri ennyangu: Mu ``Autosomal Recessive'', omwana ajja kufuna engeri/obulwadde obwo singa maama ne taata bombi basikira obuzaale "obunafu".

Ekigambo ``Autosomal`` kitegeeza ki?

`Autosomal` kitegeeza nti gene teri ku chromosome ya kikula, wabula ku chromosome eriko ennamba. Abantu balina ensengekera z’obutonde (chromosomes) 46. Ofuna 23 okuva ku maama wo ate 23 okuva ku kitaawo, n’ofuna 46. Ku zino, waliwo ensengekera z’ekikula bbiri (X ne Y). Chromosomes endala 22 za chromosomes ezirina ennamba. Chromosomes zino zokka ezirina ennamba ze zikozesa enkola ya `Autosomal` ey'obusika.

Engeri zino tuzisikira tutya? Kiki ekibaawo munda mu ffe?

Engeri zino tuzisikira okuva mu ggi lya maama waffe n’ensigo za kitaffe. Bino birimu obuzaale bwaffe. Enkola nzibu nnyo. Ka tulabe ebitundu byayo ebikulu:

• ( DNA ): Eno ye molekyu enkulu etereka amawulire agakwata ku buzaale bwaffe.
• Ensengekera z’obuzaale : Bino bye bitundu ebitongole ebya DNA. Buli ggiini y’esalawo engeri zaffe ssekinnoomu.
• Chromosomes : Zino nsengekera ezikolebwa emiguwa mingi egya DNA. Ensengekera z’obuzaale zisangibwa munda mu nsengekera z’obutonde (chromosomes) zino.

Lowooza ku kino: chromosomes ziringa ebitabo. DNA eringa ebitabo ebiri ku bishalofu ebyo. Obuzaale bufaananako essuula eziri mu bitabo ebyo. Ofuna kkopi emu ey’obuzaale okuva ku maama wo ate kkopi emu okuva ku kitaawo. Ekyo kitondekawo obuzaale bubiri. Obuzaale buno buli munda mu butoffaali bwo. Obutoffaali buno bweyawukana ne bukola kkopi, ekifuula omubiri gwo gwonna. Obutoffaali bwe bwawukana, ensengekera z’obutonde (chromosomes) n’obuzaale (genes) birina okuba bye bimu mu buli katoffaali. Kyokka, oluusi, obutoffaali buno bwe bwawukana, wayinza okubaawo ensobi mu kugabanyaamu obuzaale. Ekyo kye tuyita enkyukakyuka. Kino kiyinza okukyusa enkola y’akatoffaali ako.

Engeri zino ze tusikira zikwata zitya ku mibiri gyaffe?

Engeri z’obusika ze zisalawo endabika yo ey’omubiri, engeri gy’olabika, n’ebyo ebikufuula ow’enjawulo ku balala. Oluusi, ensobi mu kugabanya obutoffaali eyinza okuleeta enkyukakyuka mu buzaale mu DNA yo. Enkyukakyuka zino zisobola okuleeta endwadde z’obuzaale. Kino kitegeeza nti engeri obutoffaali gye bukulamu n’okukolamu esobola okukyuka. Kyokka, si nkyukakyuka zonna nti zireeta endwadde. Enkyukakyuka ezimu tezireeta bulwadde, naye enkyukakyuka ezimu ziyinza okuleeta endwadde ez’amaanyi.

`(DNA)` esangibwa wa mu mubiri gwaffe?

DNA eri kumpi mu buli katoffaali mu mubiri gwo. Ebiseera ebisinga kiba munda mu nyukiliya, nga kino kye kifo ekifuga obutoffaali. Okolebwa obuwumbi n’obuwumbi bw’obutoffaali.

`(DNA)` eringa etya?

DNA yo ekolebwa ebika bya base bina: adenine (A), cytosine (C), thymine (T), ne guanine (G). Base zino ziyungibwa wamu okukola base pairs: A ne T, ne C ne G. Base pair zino, awamu ne molekyo ya ssukaali ne molekyo ya phosphate (eyitibwa nucleotide), zikola ensengekera eringa spiral eyitibwa double helix. Base pairs ze madaala g’amadaala, ate molekyu za ssukaali ne phosphate ze madaala agali ku njuyi zombi ez’amadaala. Ekyo si kyewuunyisa?

Enkyukakyuka ekyusa etya DNA?

Enkyukakyuka mu buzaale eyinza okubaawo ng’obutoffaali bweyawuddemu oba ng’obutoffaali bufunye ekintu eky’obutwa. Enkyukakyuka y’enkyukakyuka mu nsengekera ya DNA eya double helix. Kino kitegeeza nti ensengekera y’obutonde (gene) si we yandibadde ku chromosome. Waliwo engeri enkulu eziwerako enkyukakyuka gye ziyinza okubaawo:

• Okukyusakyusa: Nyukiliyotayidi emu ekyusibwamu endala.
• Okuyingiza: Nucleotide endala eyongerwa ku luwuzi lwa DNA.
• Okusazaamu: Nyukiliyotayidi eggyibwa mu lujegere lwa DNA.

Ne bwe kiba nti enkyukakyuka entono nga eno esobola okukosa ennyo.

Endwadde ki enkulu ez'obuzaale ezisikira mu ngeri ya ``Autosomal Dominant''?

Waliwo endwadde z’obuzaale eziwerako ezisikira mu nkola eno. Ebimu ku byokulabirako bye bino:

• Obulwadde bwa Huntington
• Obulwadde bwa Marfan syndrome
• Achondroplasia (embeera ereetera omuntu okubeera omumpi) .

Endwadde ki enkulu ez'obuzaale ezisikira nga ``Autosomal Recessive''?

Waliwo n’endwadde z’obuzaale ezisikira mu nkola eno. Bino bye bimu ku byokulabirako:

• Obulwadde bwa Cystic fibrosis
• Obulwadde bwa sickle cell
• Obulwadde bwa Tay- Sachs

Amannya gano gayinza okuwulikika nga ga kyewuunyo katono, naye gano ge mannya abasawo ge bakozesa. Bw’oba ​​owuliddeko ekintu nga kino, kati omanya nti kya buzaale.

Waliwo okukebera okukebera obulamu bw’obuzaale bwaffe?

Yee, waliwo okukebera okw’enjawulo okuzuula ebizibu by’obuzaale. Okukebera obuzaale kuyinza okuzuula enkyukakyuka mu buzaale bwo, chromosomes, oba proteins. Ebigezo bino bisobola okuzuula obuzaale obukyusiddwa obuleeta embeera z’obuzaale. Okusingira ddala, okukebera kuno kuyamba abazadde abateekateeka okuzaala okutegeera akabi akali mu kusiiga obulwadde obw’obuzaale mu baana baabwe.

Endwadde zino ez'obuzaale teziyinza kuziyizibwa kusiigibwa mu baana?

Mu butuufu, tetusobola kulonda buzaale ki bwe twagala okubuyisa mu baana baffe. N’olwekyo tekisoboka kutangira ddala ndwadde za buzaale kusiigibwa mu baana baffe. Kyokka singa wabaawo obulwadde obw’obuzaale mu maka go, osobola okwogera n’omusawo wo ku ky’okukebera obuzaale okutegeera akabi k’olina okubuyisa mu mwana wo. Osobola n’okusisinkana omukugu mu kubuulirira ku buzaale ne bateesa ku bivudde mu kukeberebwa n’okugonjoola ebikweraliikiriza byonna by’oyinza okuba nabyo.

Tukuuma tutya ``DNA'' yaffe nga nnungi?

Wadde nga tetusobola kukyusa buzaale bwe tusikira, tusobola okukola ebintu ebimu okukendeeza ku kwonooneka kwa DNA yaffe, kwe kugamba, okutondebwawo kw’enkyukakyuka empya.

• Lya emmere ennungi era ey’enjawulo. Okulya emmere erimu ebiriisa kikulu nnyo.
• Dduyilo. Omubiri gwo gukuume nga gukola.
• Tonywa ssigala . Okunywa sigala kiyinza okwonoona DNA.
• Kendeeza ku mwenge gw’onywa.
• Funa okukyalira obulamu obulungi buli kiseera olwo ebizibu byonna bisobole okuzuulibwa nga bukyali.

Jjukira nti wadde ebintu bino bisobola okukendeeza ku kwonooneka okupya ku ``(DNA)'' yaffe, tebisobola kukyusa buzaale bwe twasikira.

Obubaka Obusembayo Okutwala Awaka

Obuzaale bwe tusikira okuva mu bazadde baffe butufuula abantu ab’enjawulo. Embeera z’obuzaale zisobola okusikira mu ngeri ez’enjawulo. `(Autosomal Dominant)` ne `(Autosomal Recessive)` ze ngeri bbiri enkulu. Bw’oba ​​olina essuubi ly’okuzaala, kikulu nnyo okwogera n’omusawo wo oba omukugu mu kubuulirira ku buzaale oba mu maka go mulimu obulwadde bw’obuzaale. Olwo osobola okufuna okutegeera okutegeerekeka obulungi ku kabi kwo, ebigezo ebiyinza okukolebwa, n’emitendera gy’olina okuddako okukwata. Nsuubira nti amawulire gano gajja kuba ga mugaso gy’oli. Bw’oba ​​olina ekibuuzo kyonna, tokwatibwa nsonyi kubuuza musawo. Sigala nga oli mulamu bulungi!
