Messenger RNA ( mRNA ) = Español. Messenger RNA ( mRNA ) yog ib leeg-stranded RNA molecule uas yog ntxiv rau ib qho ntawm DNA strands ntawm cov noob. Cov mRNA yog RNA version ntawm cov noob uas tawm hauv lub cell nucleus thiab txav mus rau cytoplasm qhov twg cov proteins raug tsim.
Piv txwv li, mRNA yog dab tsi?
Txhua DNA ib ntus uas thaum kawg xaus li cov protein yog ib qho piv mRNA . Txhua DNA ib ntus uas thaum kawg xaus li cov protein yog ib qho piv mRNA . Cov tub txib RNA los yog mRNA Nws tsuas yog ib qho kev thauj mus los ntawm cov ntaub ntawv qhia txog dab tsi los ntawm cov nucleus mus rau ribosomes.
Ib yam li ntawd, tus qauv ntawm mRNA yog dab tsi? Ib mRNA molecule yog luv luv, ib leeg-stranded molecule uas muaj adenine, cytosine, guanine thiab uracil, exons, 5'-cap thiab 3'-poly-tail. Introns tau spliced tawm los ntawm cov mRNA nws tus kheej los yog los ntawm spliceosome.
Ib yam li ntawd, tib neeg nug, mRNA txhais li cas?
Neeg xa xov liaison RNA
Lub luag haujlwm ntawm mRNA yog dab tsi?
Messenger RNA ( mRNA ) nqa cov ntaub ntawv genetic luam los ntawm DNA nyob rau hauv daim ntawv ntawm ib tug series ntawm peb-base code "cov lus," txhua yam uas qhia txog ib tug tshwj xeeb amino acid. Hloov RNA (tRNA) yog tus yuam sij rau kev txiav txim siab cov lus code hauv mRNA.

Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
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)
Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Cov kauj ruam ntawm mitosis yog dab tsi thiab dab tsi tshwm sim hauv txhua qhov?
Mitosis muaj tsib theem sib txawv: interphase, prophase, metaphase, anaphase thiab telophase. Cov txheej txheem ntawm cell faib tsuas yog ua tiav tom qab cytokinesis, uas tshwm sim thaum lub sij hawm anaphase thiab telophase. Txhua theem ntawm mitosis yog tsim nyog rau cell replication thiab faib
