Cov nucleotide sequences uas ua DNA yog "code" rau cov cell ua kom ntau pua hom protein ntau; nws yog cov proteins uas muaj nuj nqi rau tswj thiab tswj cell kev loj hlob, kev faib, kev sib txuas lus nrog lwm tus hlwb thiab feem ntau lwm yam cellular functions . Cov txheej txheem no hu ua protein synthesis.
Kuj paub, DNA tseem ceeb rau lub cell li cas?
Txhua tus paub cellular lub neej thiab qee cov kab mob muaj DNA . Lub luag haujlwm tseem ceeb ntawm DNA hauv cell yog lub sij hawm ntev cia cov ntaub ntawv. Nws feem ntau muab piv rau daim ntawv qhia, txij li nws muaj cov lus qhia los tsim lwm yam ntawm cov khoom cell , xws li cov proteins thiab RNA molecules.
Tsis tas li ntawd, 3 lub luag haujlwm ntawm DNA yog dab tsi? Peb lub luag haujlwm tseem ceeb ntawm DNA yog raws li hauv qab no.
- Txhawm rau tsim cov protein thiab RNA.
- Txhawm rau pauv cov khoom siv caj ces ntawm niam txiv chromosomes thaum lub sij hawm meiotic cell division.
- Txhawm rau pab txhawb kev hloov pauv tshwm sim thiab txawm tias hloov pauv hloov pauv hauv ib khub nucleotide, hu ua point mutation.
Kuj paub, DNA tswj cov yam ntxwv li cas?
DNA nqa tag nrho cov ntaub ntawv rau koj lub cev yam ntxwv , qho yog tseem ceeb txiav txim los ntawm cov proteins. Yog li ntawd, DNA muaj cov lus qhia ua kom muaj protein ntau. Hauv DNA , txhua cov protein yog encoded los ntawm ib tug gene (ib theem zuj zus ntawm DNA nucleotides uas qhia meej li cas ib qho protein yog yuav tau ua).
Yuav ua li cas cov noob hauv DNA tswj cov hlwb?
- Cov noob nqa cov lus qhia ua cov protein. - Cov noob nqa cov lus qhia rau cell kev faib. - Cov noob nqa cov lus qhia rau kev luam DNA.

Yuav ua li cas koj thiaj paub tias ib yam dab tsi muaj nuj nqi los yog tsis?
LUS TEB: Cov lus teb piv txwv: Koj tuaj yeem txiav txim siab seb txhua lub ntsiab lus ntawm lub npe yog ua ke nrog ib qho ntawm qhov ntau. Piv txwv li, yog tias muab ib daim duab, koj tuaj yeem siv qhov ntsuas kab ntsug; Yog hais tias ib txoj kab ntsug hla cov duab ntau dua ib zaug, ces qhov kev sib raug zoo uas cov duab sawv cev tsis yog ib qho haujlwm
Yuav ua li cas koj txiav txim siab yog hais tias ib tug muaj nuj nqi muaj ib tug kab rov tav tangent?
Kab rov tav kab muaj txoj kab nqes ntawm xoom. Yog li ntawd, thaum lub derivative yog xoom, cov kab tangent yog kab rov tav. Txhawm rau nrhiav cov kab kab rov tav tangent, siv qhov derivative ntawm txoj haujlwm los nrhiav qhov xoom thiab ntsaws lawv rov qab rau hauv qhov sib npaug qub
Puas muaj qhov cubic muaj nuj nqi inverse?
QHOV CHAW UA HAUJ LWM, tsis muaj qhov hloov pauv, yog tias nws tsis yog IB-rau-ib qho kev ua haujlwm., vim tias tsuas yog cov haujlwm no yog invertible. ? Tab sis yog hais tias ib tug cubic functionis yog cov nram qab no daim ntawv / tuaj yeem hloov mus rau hauv daim ntawv hauv qab no, nws yog invertible: (i) f(x)=(ax+b)³+c, a≠0, b,c∈|R , nrog nws cov natural domain, x∈|R los yog tus nqi txo
Yuav ua li cas koj thiaj nrhiav tau tus nqi siab tshaj plaws ntawm lub quadratic muaj nuj nqi?
Yog tias koj tau txais cov mis y = ax2 + bx + c, ces koj tuaj yeem pom tus nqi siab tshaj plaws uas siv cov mis max = c- (b2 / 4a). Yog tias koj muaj qhov sib npaug y = a (x-h) 2 + k thiab theatrem tsis zoo, ces qhov siab tshaj plaws yog k
Yuav ua li cas koj thiaj paub tias muaj nuj nqi yog lub zog muaj nuj nqi?
VIDEO Ib yam li ntawd, tib neeg nug, dab tsi ua rau lub zog ua haujlwm? A lub zog ua haujlwm yog a muaj nuj nqi qhov twg y = x ^n qhov twg n yog tus lej tiag tiag. Ntau tus niam txiv muaj nuj nqi xws li linear muaj nuj nqi thiab quadratic muaj nuj nqi yog qhov tseeb lub zog ua haujlwm .
