Ib yam li ntawd, tib neeg nug, koj piav qhia txog kev hloov pauv hauv lej li cas?
Muaj plaub yam tseem ceeb ntawm kev hloov pauv : translation, rotation, reflection and dilation. Cov no kev hloov pauv poob rau hauv ob pawg: nruj kev hloov pauv uas tsis hloov cov duab lossis qhov loj ntawm qhov preimage thiab tsis nruj kev hloov pauv uas hloov qhov loj me tab sis tsis zoo li tus preimage.
Tsis tas li, koj piav qhia txog kev hloov pauv li cas? A xav txog zoo li tso daim iav rau ntawm nplooj ntawv. Thaum twg piav txog kev xav , koj yuav tsum tau hais cov kab uas cov duab tau xav txog in. Qhov kev ncua deb ntawm txhua qhov taw tes ntawm ib daim duab los ntawm kab ntawm xav txog yuav zoo ib yam li qhov kev ncua deb ntawm lub xav txog taw tes los ntawm kab.
Ntawm no, ib tug txhais lus yog dab tsi?
Kev txhais lus yog ib lo lus uas siv nyob rau hauv geometry los piav txog ib tug muaj nuj nqi uas txav ib yam khoom ib tug tej yam kev ncua deb. Cov khoom no tsis hloov mus rau lwm txoj kev. Nws tsis yog rotated, reflected los yog re-loj.
Koj sau qhov kev hloov pauv li cas?
Lub luag haujlwm txhais lus / kev hloov pauv txoj cai:
- f (x) + b hloov cov haujlwm b mus rau sab saud.
- f (x) – b hloov txoj haujlwm b mus rau nqes.
- f (x + b) hloov cov haujlwm b mus rau sab laug.
- f (x – b) hloov cov haujlwm b mus rau sab xis.
- -f (x) qhia txog kev ua haujlwm hauv x-axis (uas yog, upside-down).

Koj piav qhia txog kev hloov pauv hauv cov kab mob li cas?
Cov khoom ntawm DNA lossis cov noob paj noob hlis yog txiav los ntawm nws qhov qub DNA uas siv cov enzyme txwv thiab tom qab ntawd muab tso rau hauv plasmid los ntawm ligation. Lub plasmid uas muaj cov DNA txawv teb chaws yog tam sim no npaj tau muab tso rau hauv cov kab mob. Txoj kev no hu ua transformation
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
Yuav ua li cas koj thiaj paub tias kev hloov pauv yog ib qho rau ib qho?
Thaum ib tug linear transformation yog piav nyob rau hauv lub sij hawm ntawm ib tug matrix nws yog ib qho yooj yim los txiav txim seb lub linear transformation yog ib-rau-ib los yog tsis los ntawm kev tshuaj xyuas cov linear dependence ntawm txhua kab ntawm lub matrix. Yog hais tias cov kab yog linearly ywj siab, linear transformation yog ib-rau-ib
Thaum ib qho kev sib cais ua rau muaj kev hloov pauv hloov pauv ntawm lub ntiaj teb nce ntxiv?
Txij li thaum lub kaw lus raug cais tawm, tsis muaj cua sov tuaj yeem khiav tawm (tus txheej txheem yog li adiabatic), yog li thaum lub zog ntws tawm hauv lub cev, qhov entropy ntawm qhov system nce, piv txwv li Δ Ssys> 0. Yog li ntawd, lub entropy ntawm lub system yuav tsum tau nce rau ib tug spontaneous txheej txheem nyob rau hauv no cais system
Koj piav qhia txog kev hloov pauv li cas?
Kev hloov noob caj noob ces yog kev hloov pauv mus tas li hauv DNA ib ntus uas ua rau cov noob, xws li qhov sib txawv ntawm cov neeg feem coob. Kev hloov pauv ntau hauv qhov loj; lawv tuaj yeem cuam tshuam qhov twg los ntawm ib qho DNA tsev thaiv (hauv paus khub) mus rau ib ntu loj ntawm chromosome uas suav nrog ntau cov noob
