Lub hauv paus ntsiab lus ntawm complementarity: lub essence ntawm lub tswvyim thiab qhov yooj yim cov kev cai ntawm noob caj noob ces

Complementarity - cov cuab yeej no yog ob lug sib haum mus rau txhua lub lwm yam nyob rau hauv ib tug tshwj xeeb txoj kev.

complementarity ntsiab cai pom daim ntawv thov nyob rau hauv ntau yam spheres ntawm tib neeg kev ua si. Yog li ntawd, lub essence ntawm complementarity nyob rau hauv txoj kev kawm rau lub caij nyoog yam ntxwv ntawm cov tsim thiab kev loj hlob ntawm cov tub ntxhais kawm nyob rau hauv lub tej yam kev mob ntawm cov kev kawm hauv tsev qauv. Nyob rau hauv lub cheeb tsam ntawm creativity Composers nws yog txuam nrog citations thiab nyob rau hauv Science News for KIDS active hauv paus ntsiab lus yog ib tug sib phim spatial lug ntawm ob tug sib txawv molecules, uas tej zaum yuav tshwm sim nruab nrab ntawm cov hydrogen tsevneeg thiab intermolecular sis raug zoo.

lub hauv paus ntsiab lus ntawm complementarity hauv ib kev txhawj xeeb kev ruaj ntseg ntawm biopolymer molecules thiab lawv sib txawv tawg tsam. Nws kom cov tsim ntawm ib tug meej kev twb kev txuas ntawm lawv (e.g., hydrophobic los yog electrostatic kev sib tshuam ntawm cov them functional pawg).

Yog li complementary tawg tsam thiab khi biopolymers tsis covalent tshuaj daim ntawv cog lus thiab spatial xov xwm rau txhua lwm yam mus rau tsim tsis muaj zog mus uas collectively muaj lub siab lub zog, uas ua rau tsim ntawm ib tug txaus ruaj khov ceg ntawm molecules. Nyob rau hauv cov ntaub ntawv no, lub catalytic kev ua si ntawm tshuaj yog nyob rau ntawm lawv cov complementarity nrog lub intermediate catalytic tshua.

Kuv yuav tsum hais tias muaj kuj yog ib tug notion ntawm cov yam ntxwv xov xwm ntawm ob tebchaw. Piv txwv li, thaum lub intermolecular sis ntawm protein complementarity hauv paus ntsiab lus - ib tug tseem ligand mus kom ze txhua lwm yam nyob rau ib lub ze ze uas muab ib tug muaj zog sib txuas ntawm lawv.

Lub hauv paus ntsiab lus ntawm complementarity nyob rau hauv lub tshav pob ntawm kev tshuaj ntsuam genetic kev txhawj xeeb replication (doubling) ntawm DNA. Txhua saw ntawm cov qauv yuav pab raws li ib tug template uas yog siv nyob rau hauv lub synthesis ntawm complementary strands hais tias cov theem kawg tso cai rau kom muab tau replicas ntawm tus thawj deoxyribonucleic acid. Nyob rau tib lub sij hawm muaj yog ib tug ntshiab xov xwm ntawm lub nitrogenous bases, qhov twg adenine uake rau thymine, thiab guanine - nrog cytosine xwb.

Oligo thiab polynucleotides nitrogenous bases tsim ib tug coj khub ceg - T-A (A-U nyob rau hauv RNA) los yog D-C los ntawm reacting ob strands ntawm nucleic acids. Qhov no txoj ntsiab cai ntawm complementarity plays ib tug tseem ceeb luag hauj lwm nyob rau hauv kom siv cov txheej txheem ntawm cia thiab hloov lwm lub tsev ntawm kev tshuaj ntsuam genetic ntaub ntawv. Yog li, ob npaug ntawm DNA thaum lub sij hawm cell division, lub DNA nyob rau hauv lub RNA transcription txheej txheem uas yuav siv sij hawm qhov chaw thaum lub protein synthesis thiab kho dab (yuav txo tau) ntawm DNA puas tsuaj tom qab tsis yooj yim sua yam uas tsis tau ua raws li txoj ntsiab cai no.

Thaum twg irregularities nyob rau hauv nruj me ntsis predetermined xov xwm ntawm ib qho tseem ceeb qhov chaw ntawm txawv molecules nyob rau hauv lub cev muaj ib tug pathology uas yog clinically manifested caj kab mob. Lawv muaj peev xwm yuav kis tau mus xeeb leej xeeb ntxwv los yog yuav incompatible nrog lub neej.

- Nyob rau hauv tas li ntawd, ib tug tseem ceeb soj ntsuam raws li nyob rau hauv lub hauv paus ntsiab lus ntawm komplementaranosti PCR (polymerase chain reaction). Nrog kev tshuaj ntsuam genetic detectors ntes DNA los yog RNA ntawm ntau yam pathogens los yog kab mob viral mob nyob rau hauv tus txiv neej, uas yuav pab muab kev kho mob raws li lesion etiology.
