Kev txhais lus : Pib, nruab nrab, thiab xaus
Kev txhais lus muaj ntau yam zoo tib yam peb ntu, tab sis lawv muaj lub npe zoo: pib, elongation, thiab xaus. Initiation ("pib"): nyob rau theem no, lub ribosome tau ua ke nrog mRNA thiab thawj tRNA thiaj li txhais lus tuaj yeem pib
Ib yam li ntawd, 5 kauj ruam ntawm kev sau ntawv yog dab tsi?
RNA tom qab ntawd nkag mus rau kev txhais lus los ua cov protein. Cov kauj ruam tseem ceeb ntawm kev sau ntawv yog pib , txhawb kev tshem tawm, elongation , thiab kev txiav txim.
Tsis tas li ntawd, cov kauj ruam ntawm kev txhais lus hauv eukaryotes yog dab tsi? Eukaryotic txhais lus yog cov txheej txheem lom neeg uas tus tub txib RNA tau muab txhais ua cov protein hauv eukaryotes. Nws muaj plaub theem: pib , elongation, termination, thiab recycling.
Yog li ntawd, dab tsi tshwm sim hauv txhua theem ntawm kev txhais lus?
Kev txhais lus mRNA molecule los ntawm ribosome tshwm sim hauv peb theem : pib, elongation, thiab termination. Thaum lub sij hawm elongation theem , lub ribosome tseem txhais txhua codon nyob rau hauv lem. Txhua Cov amino acid sib raug tau ntxiv rau cov saw loj hlob thiab txuas ntawm a daim ntawv cog lus hu ua a peptide daim ntawv cog lus.
Tus txheej txheem ntawm kev txhais lus yog dab tsi?
Kev txhais lus yog cov txheej txheem ntawm kev txhais lus qhov sib lawv liag ntawm tus tub txib RNA (mRNA) molecule rau ib theem ntawm cov amino acids thaum lub sij hawm cov protein synthesis. Cov noob caj noob ces piav qhia txog kev sib raug zoo ntawm qhov sib lawv liag ntawm lub hauv paus khub hauv ib lub noob thiab cov amino acid sib txuas uas nws encodes.

Dab tsi yog 6 kauj ruam ntawm kev txhais lus?
Kev txhais lus (biology) Pib: Lub ribosome sib sau ua ke ib ncig ntawm lub hom phiaj mRNA. Thawj tRNA txuas rau ntawm qhov pib codon. Elongation: Lub tRNA hloov cov amino acid mus rau tRNA sib raug rau cov codon tom ntej. Kev Txiav Txim: Thaum peptidyl tRNA ntsib qhov nres codon, ces lub ribosome folds cov polypeptide rau hauv nws cov qauv kawg
Thawj kauj ruam ntawm kev ua pa ntawm tes yog dab tsi thiab nws tshwm sim qhov twg?
Glycolysis
Dab tsi yog cov kauj ruam los daws qhov tsis sib xws ntawm ob kauj ruam?
Nws yuav siv ob kauj ruam los daws qhov kev sib npaug lossis qhov tsis sib xws uas muaj ntau tshaj ib qho kev ua haujlwm: Simplify siv qhov sib txawv ntawm qhov sib ntxiv lossis rho tawm. Ua kom yooj yim ntxiv los ntawm kev siv qhov sib txawv ntawm qhov sib npaug lossis faib
Dab tsi yog thawj kauj ruam ntawm kev tsim ib qho perpendicular los ntawm ib qho taw tes mus rau kab?
Txuas tus taw tes rau qhov taw tes uas cov arcs sib tshuam. Siv ib tug straightedge los xyuas kom meej cov kab yog ncaj. Txoj kab koj kos yog perpendicular rau thawj kab, los ntawm qhov muab taw tes rau ntawm kab
Koj ua li cas electron configuration kauj ruam yog kauj ruam?
Cov kauj ruam Nrhiav koj tus lej atomic. Txiav txim siab tus nqi ntawm lub atom. Nco cov npe ntawm cov orbitals. Nkag siab txog kev teeb tsa hluav taws xob. Nco qhov kev txiav txim ntawm lub orbitals. Sau rau hauv lub orbitals raws li tus naj npawb ntawm electrons hauv koj lub atom. Siv lub sij hawm ntev raws li qhov pom kev luv luv
