Nws yog heev tseem ceeb tias kev tshawb fawb tuaj yeem rov ua dua, vim nws txhais tau hais tias lwm cov kws tshawb fawb tuaj yeem kuaj qhov kev tshawb pom ntawm kev tshawb fawb. Replicability ua kom cov neeg tshawb nrhiav ncaj ncees thiab tuaj yeem ua rau cov neeg nyeem kev ntseeg siab hauv kev tshawb fawb. Yog kev tshawb fawb hloov tau , tom qab ntawd txhua qhov kev txiav txim tsis raug thaum kawg tuaj yeem pom tias tsis yog.
Tom qab ntawd, ib tus tuaj yeem nug, qhov kev hloov pauv txhais li cas hauv kev puas siab puas ntsws?
Replicability yog ib qho tseem ceeb ntawm kev tshawb fawb. Nws txhais tau tias tias ib qho kev tshawb fawb yuav tsum tsim cov txiaj ntsig zoo ib yam yog tias rov ua raws nraim, los ntawm tib tus kws tshawb fawb lossis lwm tus.
Kev tshawb fawb txog kev hloov pauv yog dab tsi? Kev tshawb fawb yog hloov tau thaum ib pab neeg ywj pheej ntawm cov kws tshawb fawb tuaj yeem luam cov txheej txheem tib yam thiab tuaj txog ntawm cov txiaj ntsig zoo ib yam li tus thawj kawm . Empirical generalizations yog cov txiaj ntsig uas tsis tuaj yeem rov ua dua los ntawm kev ywj pheej cov kws tshawb fawb siv siv tau, tab sis txawv, txoj kev.
Dhau li saum toj no, vim li cas replication tseem ceeb hauv kev puas siab puas ntsws?
Rov ua dua yog li ntawd, yog tseem ceeb rau ntau qhov laj thawj, suav nrog (1) kev lees paub tias cov txiaj ntsig tau siv tau thiab ntseeg tau; (2) kev txiav txim siab ntawm generalizability los yog lub luag hauj lwm ntawm extraneous variables; (3) kev siv cov txiaj ntsig rau cov xwm txheej hauv ntiaj teb tiag; thiab (4) kev tshoov siab ntawm kev tshawb fawb tshiab sib txuas cov kev tshawb pom yav dhau los los ntawm
Vim li cas thiaj muaj Replication ntsoog hauv kev puas siab puas ntsws?
Qhov kev rov ua dua tshiab tau sib tham dav dav hauv tus teb ntawm kev puas siab puas ntsws thiab nyob rau hauv cov tshuaj, qhov twg ib tug xov tooj ntawm kev siv zog tau ua rau rov tshawb xyuas cov txiaj ntsig classic, los txiav txim rau ob qho tib si tus kev ntseeg ntawm tus cov txiaj ntsig, thiab, yog tias pom tias tsis ntseeg tau, tus vim li cas tus tsis ua hauj lwm ntawm rov ua dua.

Dab tsi yog txoj hauv kev lom neeg hauv kev puas siab puas ntsws?
Kev pom kev lom neeg yog ib txoj hauv kev los saib cov teeb meem puas siab puas ntsws los ntawm kev kawm lub hauv paus rau tsiaj thiab tib neeg tus cwj pwm. Nws yog ib qho ntawm cov kev xav loj hauv kev puas siab puas ntsws thiab muaj xws li kev kawm lub hlwb, lub cev tsis muaj zog, lub paj hlwb, thiab caj ces
Vim li cas tom qab kev hloov pauv kev hloov pauv tseem ceeb?
Kev hloov pauv tom qab kev txhais lus (PTMs) xws li glycosylation thiab phosphorylation ua lub luag haujlwm tseem ceeb ntawm kev ua haujlwm ntawm hemostatic proteins thiab tseem ceeb heev hauv kev teeb tsa kab mob. Xws li theem nrab hloov pauv rau cov proteins hemostatic muaj ntau yam cuam tshuam rau lawv lub peev xwm los cuam tshuam nrog lwm cov proteins
Vim li cas qhov tseem ceeb ntawm qhov tseem ceeb?
Thaum koj pom tus nqi kiag li hauv qhov teeb meem lossis qhov sib npaug, nws txhais tau hais tias txhua yam nyob hauv tus nqi tiag tiag yog qhov zoo. Cov txiaj ntsig tsis zoo feem ntau siv rau hauv cov teeb meem cuam tshuam nrog kev nyob deb thiab qee zaum siv nrog qhov tsis sib xws. Qhov ntawd yog qhov tseem ceeb uas yuav tsum nco ntsoov nws zoo li qhov deb ntawm xoom
Dab tsi tsim cov roj siab thiab nws hloov pauv li cas nrog kev hloov pauv hauv kinetic zog?
Gas siab yog tshwm sim los ntawm kev sib tsoo ntawm cov khoom siv roj nrog rau sab hauv ntawm lub thawv thaum lawv sib tsoo nrog thiab tawm dag zog rau ntawm phab ntsa ntim. Tom qab ntawd cov roj yog cua sov. Raws li qhov kub ntawm cov roj nce, cov khoom tau nce lub zog kinetic thiab lawv cov nrawm nrawm
Peb qhov laj thawj tseem ceeb ntawm kev hloov pauv hloov pauv yog dab tsi?
Allele frequencies nyob rau hauv ib tug pej xeem yuav hloov vim plaub lub hauv paus zog ntawm evolution: Natural Selection, Genetic Drift, Mutations thiab Gene Flow. Kev hloov pauv yog qhov kawg ntawm cov alleles tshiab hauv cov noob caj noob ces. Ob ntawm cov txheej txheem tseem ceeb tshaj plaws ntawm kev hloov pauv hloov pauv yog: Natural Selection thiab Genetic Drift
