Kev ua kom tiav yog cov cuab yeej ntawm ob lub qauv kom phim ib qho tshwj xeeb.
Lub hauv paus ntsiab lus ntawm kev sib ntxiv pom muaj kev thov hauv ntau yam kev ua haujlwm ntawm tib neeg. Yog li, qhov tseem ceeb ntawm kev ua tiav hauv cov txheej txheem kev kawm cuam tshuam txog cov yam ntxwv ntawm kev tsim thiab kev loj hlob ntawm cov tub ntxhais kawm nyob rau hauv cov ntsiab lus ntawm cov qauv kev kawm hauv tsev kawm ntawv. Nyob rau hauv lub teb ntawm composers 'creativity, nws yog txuam nrog kev siv ntawm citations, thiab nyob rau hauv chemistry lub ntsiab cai no yog lub spatial correspondence ntawm cov qauv ntawm ob txawv molecules, ntawm uas hydrogen bonds thiab intermolecular kev sib cuam tshuam yuav tshwm sim.
Lub hauv paus ntsiab lus ntawm kev sib ntxiv hauv biology cuam tshuam txog kev sib txuam ntawm biopolymer molecules thiab lawv cov khoom sib txawv. Nws ua kom muaj kev sib raug zoo ntawm lawv (piv txwv li, hydrophobic lossis electrostatic kev sib cuam tshuam ntawm pawg neeg ua haujlwm raug them).
Nyob rau hauv cov ntaub ntawv no, complementary fragments thiab biopolymers tsis yog khi los ntawm covalent tshuaj daim ntawv cog lus, tab sis los ntawm spatial correspondence rau ib leeg nrog tsim ntawm tsis muaj zog bonds, uas nyob rau hauv tag nrho muaj ntau dua.lub zog, uas ua rau kev tsim ntawm txaus ruaj khov complexes ntawm molecules. Hauv qhov no, kev ua haujlwm catalytic ntawm cov tshuaj nyob ntawm lawv qhov sib ntxiv nrog cov khoom nruab nrab ntawm cov tshuaj tiv thaiv catalytic.
Nws yuav tsum tau hais tias tseem muaj lub tswv yim ntawm kev sib txuas lus ntawm ob lub tebchaw. Yog li, piv txwv li, hauv kev sib cuam tshuam ntawm cov proteins, lub hauv paus ntsiab lus ntawm kev sib xyaw ua ke yog lub peev xwm ntawm ligands mus rau ib leeg nyob ze, uas ua kom muaj kev sib raug zoo ntawm lawv.
Lub hauv paus ntsiab lus ntawm kev sib ntxiv hauv cov caj ces cuam tshuam txog cov txheej txheem ntawm DNA replication (ob npaug). Txhua txoj hlua ntawm cov qauv no tuaj yeem ua tus qauv, uas yog siv rau hauv kev sib txuas ntawm cov hlua txuas ntxiv, uas nyob rau theem kawg ua rau nws tuaj yeem tau txais cov ntawv luam ntawm tus thawj deoxyribonucleic acid. Nyob rau tib lub sijhawm, muaj kev sib raug zoo ntawm nitrogenous hauv paus, thaum adenine ua ke nrog thymine, thiab guanine - tsuas yog nrog cytosine.
Oligo- thiab polynucleotides ntawm nitrogenous hauv paus tsim cov sib txuas ua ke ua ke - A-T (A-U hauv RNA) lossis G-C thaum muaj kev cuam tshuam ntawm ob lub nucleic acid chains. Lub hauv paus ntsiab lus ntawm complementarity no ua lub luag haujlwm tseem ceeb hauv kev ua kom cov txheej txheem tseem ceeb ntawm kev khaws cia thiab xa cov ntaub ntawv ntawm caj ces. Yog li, DNA ob npaug thaum lub sij hawm faib cell, txheej txheem ntawm DNA hloov mus rau hauv RNA, uas tshwm sim thaum lub sij hawm protein synthesis, nrog rau cov txheej txheem ntawm kev kho (tso rov qab) ntawm DNA molecules tom qab lawv puas, yog tsis yooj yim sua yam tsis tau soj ntsuam.txoj ntsiab cai no.
Thaum muaj kev ua txhaum cai hauv kev sau ntawv nruj me ntsis ntawm cov khoom tseem ceeb ntawm ntau yam molecules hauv lub cev, pathologies tshwm sim uas tau kuaj pom los ntawm cov kab mob caj ces. Tej zaum lawv yuav raug xa mus rau cov xeeb ntxwv lossis tsis sib haum nrog lub neej.
Ntxiv rau, qhov kev tshuaj xyuas tseem ceeb raws li lub hauv paus ntsiab lus ntawm kev sib txuas yog PCR (polymerase saw cov tshuaj tiv thaiv). Siv cov cuab yeej kuaj kab mob tshwj xeeb, DNA lossis RNA ntawm ntau yam kab mob ntawm tib neeg kis kab mob lossis kab mob kis tau, uas yuav pab sau tshuaj kho raws li etiology ntawm qhov txhab.
