Pib thiab nres codons yog ib qho tseem ceeb vim hais tias lawv qhia lub xov tooj ntawm tes machinery qhov twg yuav pib thiab xaus kev txhais lus, tus txheej txheem ntawm kev ua ib tug protein ntau . Cov pib codon marks lub site uas txhais rau hauv protein ntau pib pib. Cov nres codon (los yog txiav tawm codon ) cim qhov chaw uas txhais lus xaus.
Hais txog qhov no, lub hom phiaj ntawm qhov pib thiab nres codons yog dab tsi?
Pib thiab nres Codons Cov pib codon cim qhov chaw ntawm qhov kev txhais lus rau hauv protein ntau pib, thiab cov nres codon cim qhov chaw uas txhais lus xaus. Peb paub li cas codon cov lej twg rau cov amino acid?
Ib tug kuj yuav nug, dab tsi yog qhov tseem ceeb ntawm qhov pib thiab nres codons quizlet? Qhov pib codon (AUG) cim qhov pib ntawm a protein ntau thiab qhov chaw txhais lus yuav tsum pib; The stop codons (UGA, UAA, and, UAG) mark the end of the protein ntau thiab qhov twg kev txhais lus yuav tsum xaus.
Tom qab ntawd, lo lus nug yog, txoj cai caj ces yuav pab tau cov protein synthesis li cas?
Lub luag hauj lwm ntawm cov noob caj noob ces hauv protein synthesis . Peb tus kws tshawb fawb tau pom tias RNA - qhov nruab nrab molecule ntawm DNA thiab cov proteins - tuaj yeem tsim peb tsab ntawv 'cov lus' nrog nws cov tshuaj hauv paus A, U, C thiab G thiab tias cov 'cov lus' tuaj yeem muab txhais ua ntu ntawm cov amino acids, lub tsev thaiv ntawm cov proteins.
Vim li cas peb thiaj li ua kom muaj qhov pib thiab nres DNA?
Yog li txhua peb tsab ntawv ua ntu zus ntawm RNA sib raug rau ib qho amino acid, a pib los yog nres codon. Pib thiab nres codons yog ib qho tseem ceeb vim tias tom qab ntawd kev txhais lus tsis pib lossis tiav. Thaum lub sij hawm synthesis protein, nres codons ua rau kev tso tawm ntawm cov protein los ntawm ribosome.

Vim li cas peb thiaj li hais txog kev txwv tsis pub muaj kev hais tawm thiab thaum twg peb yuav hais cov kev txwv?
Peb hais txog kev txwv vim nws yuav ua rau qhov sib npaug tsis tau txhais hauv qee qhov txiaj ntsig ntawm x. Qhov kev txwv ntau tshaj plaws rau cov lus qhia muaj nuj nqis yog N / 0. Qhov no txhais tau tias txhua tus lej muab faib los ntawm xoom tsis tau txhais. Piv txwv li, rau txoj haujlwm f(x) = 6/x², thaum koj hloov x = 0, nws yuav ua rau 6/0 uas tsis tau txhais
Qhov kev sib npaug twg yog qhov tsim nyog los suav cov cua sov uas tsim los ntawm HCl NaOH cov tshuaj tiv thaiv?
Xam cov naj npawb ntawm moles ntawm lub hauv paus koj ntxiv los txiav txim siab molar tshav kub ntawm qhov nruab nrab, qhia siv qhov sib npaug Δ H = Q ÷ n, qhov twg 'n' yog tus naj npawb ntawm moles. Piv txwv li, xav tias koj ntxiv 25 mL ntawm 1.0 M NaOH rau koj HCl los ua kom muaj cua sov ntawm nruab nrab ntawm 447.78 Joules
Yog vim li cas transcription yog ib kauj ruam tsim nyog nyob rau hauv protein synthesis?
Lub Art ntawm Protein Synthesis Nyob rau hauv eukaryotic hlwb, transcription tshwm sim nyob rau hauv lub nucleus. Thaum lub sijhawm sau ntawv, DNA yog siv los ua tus qauv los ua ib qho molecule of messenger RNA (mRNA). Thaum lub sij hawm kev txhais lus, cov noob caj noob ces hauv mRNA yog nyeem thiab siv los ua cov protein
Vim li cas kev sib txhuam yog tsim nyog rau kev txav mus los?
Txij li kev sib txhuam yog lub zog tiv thaiv uas ua rau qeeb lossis tiv thaiv kev txav, nws yog qhov tsim nyog hauv ntau daim ntawv thov uas koj yuav xav tuav cov khoom lossis ua tej yam thiab tiv thaiv kom tsis txhob ntog lossis zawv zawg. Yog tsis muaj kev sib txhuam, koj yuav tsis muaj peev xwm taug kev, tsav tsheb, lossis tuav cov khoom
Lub zog rau kev thauj mus los ntawm qhov twg thiab vim li cas thiaj li xav tau lub zog rau kev thauj mus los?
Kev thauj mus los nquag yog txheej txheem uas yuav tsum tau txav cov molecules tawm tsam qhov concentration gradient. Cov txheej txheem yuav tsum muaj zog. Lub zog rau cov txheej txheem tau txais los ntawm kev rhuav tshem cov piam thaj siv oxygen hauv kev ua pa aerobic. ATP yog tsim thaum ua pa thiab tso tawm lub zog rau kev thauj mus los
