Dab tsi yog qhov directionality ntawm cov protein ? Muaj ib sab carboxyl thiab amino sab thiab thaum hooked ua ke muaj ib sab rau txhua tus protein ntau . Dab tsi yog qhov tseem ceeb ntawm kev taw qhia hauv protein ntau kev zom zaub mov? Koj muaj ob lub enzymes zom cov zaub mov, ib qho ntawm txhua sab.

Hais txog qhov no, dab tsi muab cov kev taw qhia rau cov protein?

Peptide bonds Txhua protein ntau hauv koj lub hlwb muaj ib los yog ntau dua polypeptide chains. Vim yog cov qauv ntawm cov amino acids, cov saw hlau polypeptide muaj kev taw qhia , txhais tau hais tias nws muaj ob qhov kawg uas yog tshuaj sib txawv ntawm ib leeg.

Ib yam li ntawd, puas yog N terminus 5 lossis 3? Thiab RNA yog ib txwm polymerized nyob rau hauv tsib prime mus rau peb lub ntsiab lus tseem ceeb. Tam sim no nrog peb cov amino acid, peb sau qhov kawg no, uas yog peb cov amino acid qhov kawg , as N thiab qhov kawg no yog peb carboxy qhov kawg uas C.

Thiab cov lus nug yog, dab tsi yog directionality hauv biology?

Kev taw qhia , nyob rau hauv molecular biology thiab biochemistry, yog qhov kawg-rau-kawg orientation ntawm ib qho strand ntawm nucleic acid.

Cov protein zoo li cas?

Cov protein yog tsim los ntawm ntau pua lossis ntau txhiab tus me me hu ua amino acids, uas txuas rau ib leeg hauv cov saw ntev. Muaj 20 ntau hom amino acids uas tuaj yeem ua ke los ua ib qho protein ntau . Cov no cov proteins khi thiab nqa cov atoms thiab cov molecules me me hauv cov hlwb thiab thoob plaws hauv lub cev.

Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm kev taw qhia ntawm tes los ntawm kev sib cuag lub cev ncaj qha?

Kev taw qhia kuj tshwm sim ntawm cov hlwb uas yog kev sib cuag ntawm lub cev. Kev sib cuam tshuam ntawm cov proteins ntawm qhov chaw ntawm cov hlwb tuaj yeem ua rau muaj kev hloov pauv hauv cov cwj pwm ntawm tes. Piv txwv li, cov proteins nyob rau saum npoo ntawm T-cells thiab antigen nthuav tawm cov hlwb sib cuam tshuam los ua kom muaj kev taw qhia hauv T-cells

Dab tsi yog qhov txawv ntawm kev xaiv kev taw qhia thiab kev xaiv cuam tshuam?

Hauv kev xaiv cov kev taw qhia, cov pej xeem cov noob caj noob ces hloov mus rau qhov tshiab phenotype thaum raug kev hloov pauv ib puag ncig. Hauv kev sib txawv lossis kev cuam tshuam kev xaiv, qhov nruab nrab lossis nruab nrab phenotypes feem ntau tsis haum dua li qhov phenotype huab cua thiab tsis zoo li yuav ua rau muaj txiaj ntsig zoo hauv cov pej xeem

Nyob rau hauv dab tsi kev taw qhia yog qhov siab tshaj plaws ntawm kev nce?

Qhov siab tshaj plaws ntawm kev hloov pauv yog li ntawd thiab tshwm sim nyob rau hauv cov kev taw qhia ntawm gradient, $ abla f(2, 0) = (0, 2)$, thiab qhov tsawg kawg nkaus tus nqi ntawm kev hloov yog thiab tshwm sim nyob rau hauv cov kev taw qhia opposite ntawm lub gradient, uas. yog $- abla f(2, 0) = (0, -2)$. Yog li ntawd
