Qhov mRNA hauv paus yog ua pab pawg nyob rau hauv peb teev, hu ua codons. Txhua codon muaj ib tug complementary txheej hauv paus , hu ua ib anticodon. Anticodons yog ib feem ntawm kev hloov pauv RNA (tRNA) molecules.
Hauv qhov no, dab tsi 4 nitrogen bases pom hauv RNA?
Muaj plaub lub hauv paus nitrogenous pom hauv RNA : adenine, guanine, cytosine, los yog uracil. Adenine thiab guanine yog hu ua purine (def) hauv paus Thaum cytosine thiab uracil hu ua pyrimidine hauv paus (def) (saib daim duab 3).
Kuj Paub, lub npe twg yog muab rau ib pawg ntawm peb lub hauv paus ntawm mRNA uas cov lej rau cov amino acid? Txhua pab pawg ntawm peb lub hauv paus hauv mRNA tsim ib codon, thiab txhua codon qhia ib qho tshwj xeeb amino acid (li no, nws yog triplet code ). Cov mRNA yog li siv raws li ib tug template rau assemble-nyob rau hauv kev txiav txim-lub saw ntawm amino acids uas tsim cov protein.
Tsis tas li lo lus nug yog, dab tsi yog 3 qhov ntev ntawm cov hauv paus hu ua?
peb nucleotides- hu ua triplet lossis codon-codes rau ib qho amino acid hauv cov protein. Cov nucleotide ib ntus nyob rau hauv DNA yog thawj transcribed mus rau hauv ib tug molecule ntawm messenger RNA (ribonucleic acid).
Hom RNA twg muaj peb lub hauv paus nitrogen ntawm ib kawg uas paub sib sau ua Anticodon?
tRNA
Pom zoo:
Dab tsi yog pawg ntawm 3 tRNA hauv paus uas haum rau mRNA hu ua?
Lub hauv paus mRNA tau muab faib ua peb pawg, hu ua codons. Txhua codon muaj cov txheej txheem ntxiv ntawm cov hauv paus, hu ua anticodon. Anticodons yog ib feem ntawm kev hloov RNA (tRNA) molecules. Txuas rau txhua tRNA molecule yog ib qho amino acid - qhov no, cov amino acid yog methionine (met)
Dab tsi yog qhov sib txawv ntawm cov atomic loj los ntawm sab saum toj mus rau hauv qab hauv ib pab pawg?
Los ntawm sab saum toj mus rau hauv qab ib pawg, electronegativity txo. Qhov no yog vim tus naj npawb atomic nce ib pawg, thiab yog li muaj kev ncua deb ntawm valence electrons thiab nucleus, los yog ntau dua atomic radius
Dab tsi yog qhov sib lawv liag ntawm nitrogen hauv paus ntawm kev sib txuas DNA strand?
Plaub lub hauv paus nitrogenous uas tsim cov caj qaum ntawm DNA ua khub nrog lub hauv paus ua ke zoo li adenine khub nrog thymine thaum cytosine khub nrog guanine
Dab tsi yog qhov kev ntsuas ntawm lub hauv paus nyiam rau cov ntaub ntawv uas tsis yog pawg?
Lub sij hawm nruab nrab nyiam yog hais txog qhov nruab nrab, lossis ib txwm, tus nqi ntawm cov ntaub ntawv, uas feem ntau ntsuas los ntawm kev siv peb m's: txhais tau tias, nruab nrab, thiab hom. Qhov nruab nrab, nruab nrab, thiab hom yog hu ua kev ntsuas ntawm qhov nruab nrab nyiam
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
