Mabda'a complementarity: nuxurka fikradda iyo shuruucda aasaasiga ah ee genetics

Complementarity: - hantida tani tahay labo in kasta oo kale qaabab u dhigma hab khaas ah.

mabda'a complementarity helaa codsi dhinacyo kala duwan oo waxqabad aadanaha. Sidaas daraaddeed, nuxurka complementarity in nidaamka waxbarashada si sifooyinka dhabta ah ee ku formation iyo horumarinta ardayda shuruudaha mawduuca dhismeedka waxbarasho. In deegaanka ee hal-abuurka composers waxaa la xidhiidha xigashooyinka oo chemistry mabda'a firfircoon waa qaab-dhismeedka aan ollogga laba u taagoo kala duwan, taas oo laga yaabaa inuu dhaco ka dhexeeya kulan lagala kulmo hydrogen oo isdhexgal intermolecular.

mabda'a complementarity bayoolaji ku saabsan waafaqsanaanta ee u taagoo biopolymer iyo burbur ay kala duwan. Waxay hubisaa formation of xiriir la hubo u dhaxeeya (tus, isdhexgalka hydrophobic ama electrostatic u dhexeeya kooxaha ka functional eedeeyay).

jajabkii Sayidka kaabaha iyo biopolymers xidho ma bond kiimikada covalent iyo waraaqo aan ollogga midba midka kale si ay u sameeyaan links daciif ah oo si wadajir ah ay leeyihiin tamarta sare, kaas oo keena in formation of a kaxeynayo ku filan deggan ee u taagoo. Xaaladdan oo kale, waxqabadka horseed ee walxaha ku xiran yahay ay complementarity la reactions horseed dhexe.

waa inaan idhaahdo waxaa jira sidoo kale waa fikradda ah warqadihiisa dhismaha of labada xeryahooda. Tusaale ahaan, marka isdhexgalka intermolecular of protein mabda complementarity - waa awooda of ligands u dhawaadaan kasta oo kale oo meel fog ka dhow, oo bixiya xiriir xoog leh u dhaxeeya.

Mabda'a ah complementarity berrinkii walaac taranka hidde (labanlaabay) ee DNA. silsilad kasta oo qaab-dhismeedka shaqayn kartaa sida jaantuska ah oo loo isticmaalo in ereygu wuxuu ahaa ee qaybood oo dhammeystira in heerka ugu dambeeya ogolaanaya in la helo replicas ee asalka acid deoxyribonucleic. Isla mar ahaantaana waxaa jira waraaqo a cad u dhexeeya saldhigyadii nitrogenous, halkaas adenayn duubaa in thaymiin, iyo gu'anayn: - kula saytosayn oo keliya.

Oligo iyo polynucleotides saldhig nitrogenous u sameeyaan a kaxeynayo baahisey Labada nin - T-A (A-U in RNA) ama D-by C ficil laba qaybood ee acids nucleic. Tani mabda'a of complementarity kaalin muhiim ah in la hubiyo habka aasaasiga ah ee kaydinta iyo wareejinta macluumaad hidde. Sayidka, laabma ee DNA inta lagu jiro kala qeybinta unug, DNA ee geedi socodka RNA qoraal ah in waxey dhacdaa marka Avv borotiinka iyo geedi socodka dayactirka (hoos u dhac) ee dhaawac DNA ka dib markii aan macquul aheyn oo aan la raacayo mabda'a this.

Marka kasta oo khaladaad in waraaqaha si adag loo dejiyay dhexeeya qaybaha muhiimka ah ee u taagoo kala duwan ee jirka ku jira heley oo isu muujin Caafimaad ahaan cudurada hidde. Waxay waxaa la isugu gudbin karaa farcankiisa ama noqon karin nolol.

- Intaa waxaa dheer, falanqaynta muhiim ah wuxuu ku salaysan yahay mabda'a komplementaranosti PCR (reaction silsilad polymerase). Iyada oo qalabka hidaha gaar ah lagu ogaan DNA ama RNA ee wareer kala duwan ama cudurada viral faafa ee nin, taas oo ka caawisaa qoro daaweynta sida etiology nabar.
