Video: Dab tsi enzymes xav tau rau kev txhais lus?
2024 Tus sau: Miles Stephen | [email protected]. Kawg hloov kho: 2023-12-15 23:36
Kev txhais lus yog catalyzed los ntawm ib tug loj enzyme hu ua ribosome, uas muaj cov proteins thiab ribosomal RNA (rRNA). Kev txhais lus Kuj tseem muaj cov RNA molecules tshwj xeeb hu ua hloov RNA (t-RNA) uas tuaj yeem khi rau peb lub hauv paus codons ntawm tus xa xov RNA (mRNA) thiab tseem nqa cov amino acid uas tsim nyog los ntawm codon.
Hais txog qhov no, dab tsi yuav tsum tau rau kev txhais lus?
Cov khoom tseem ceeb xav tau kev txhais lus yog mRNA, ribosomes, tRNA thiab aminoacyl-tRNA synthetases. Thaum txhais lus mRNA nucleotide bases tau nyeem ua peb lub hauv paus codons, txhua tus lej rau ib qho amino acid.
Tsis tas li, cov enzymes twg koom nrog hauv kev txhais cov protein? Ribosomes yog cov enzyme uas ua cov txhais lus, thiab tej zaum koj tsis meej pem yog vim cov ribosomes yog tsim los ntawm ob qho tib si RNA molecules thiab cov proteins (ib ribonucleotide complex). Aminoacyl tRNA synthetases yog cov enzymes uas ua rau aminoacyl tRNAs (tRNA luv).
Tsis tas li, dab tsi enzyme xav tau rau kev hloov pauv?
RNA polymerase
Dab tsi peb molecules xav tau rau kev txhais lus?
Messenger RNA (mRNA) molecules nqa cov coding sequences rau protein ntau synthesis thiab hu ua transcripts; ribosomal RNA (rRNA) molecules tsim lub hauv paus ntawm lub cell ribosomes (cov qauv uas protein ntau synthesis tshwm sim); thiab hloov RNA (tRNA) molecules nqa cov amino acids mus rau ribosomes thaum lub sij hawm protein ntau

Dab tsi ua rau txoj kev xav zoo ib qho kev xav zoo txog kev puas siab puas ntsws?
Ib txoj kev xav zoo yog kev sib koom ua ke - nws piav qhia ntau qhov tseeb thiab kev soj ntsuam hauv ib qho qauv lossis lub hauv paus. Txoj kev xav yuav tsum yog nyob rau hauv ib yam. Ib txoj kev xav zoo yuav tsum ua qhov kev kwv yees uas tuaj yeem kuaj tau. Qhov ntau meej thiab "tseem ceeb" qhov kev xav ntawm kev kwv yees yog - qhov ntau nws nthuav tawm nws tus kheej mus rau kev dag
Dalton txoj kev xav tau ua li cas rau kev tshawb pom ntawm lwm cov ntsiab lus?
Thaum tag nrho cov atoms ntawm ib lub caij yog zoo tib yam, cov ntsiab lus sib txawv muaj atoms ntawm qhov sib txawv loj thiab loj. Dalton's atomic txoj kev xav kuj tau hais tias tag nrho cov tebchaw tau tsim los ntawm kev sib txuas ntawm cov atoms hauv qhov piv txwv. Dalton kuj tau tshaj tawm tias cov tshuaj lom neeg ua rau muaj kev hloov pauv ntawm cov atom reacting
Henri Becquerel nrhiav tau dab tsi uas ua rau nws tau txais 1903 Nobel nqi zog Nws nrhiav tau dab tsi txog lub caij uranium?
Teb: Henri Becquerel tau txais ib nrab ntawm qhov khoom plig rau nws qhov kev tshawb pom ntawm cov hluav taws xob tsis zoo. Teb: Marie Curie tau kawm txog cov hluav taws xob ntawm tag nrho cov tebchaw uas muaj cov xov tooj cua paub, suav nrog uranium thiab thorium, uas nws tom qab pom kuj tseem muaj xov tooj cua
Dab tsi ntawm daim duab yuav zoo tshaj rau kev qhia txhais tau tias rau ntau yam kev kho mob?
Ib Bar Graph. Bar graphs yog siv los sib piv cov khoom ntawm cov pab pawg sib txawv lossis taug qab kev hloov pauv sijhawm. Txawm li cas los xij, thaum sim ntsuas qhov kev hloov pauv thaum lub sijhawm, cov kab lus yog qhov zoo tshaj plaws thaum cov kev hloov pauv loj dua
