Txhua pawg ntawm peb lub hauv paus hauv mRNA tsim ib codon, thiab txhua tus codon qhia meej ib qho amino acid (li no, nws yog triplet code). Lub mRNA ib ntus yog li siv los ua tus qauv los sib sau ua ke-hauv kev txiav txim-cov saw ntawm cov amino acids uas tsim cov protein. … Ntau tus codons tuaj yeem sau rau tib cov amino acid.
Puas yog tus xa xov RNA txhua tus codon qhia ib qho tshwj xeeb?
cell: RNA: replicated los ntawm DNA
txhua nucleotide triplet (hu ua codon) qhia meej ib qho amino acid.
Tus tub txib RNA codon yog dab tsi?
A mRNA codon yog a 3 lub hauv paus khub ntev ib feem ntawm mRNA uas cov lej rau cov amino acid tshwj xeeb hauv ribosomes ntawm ib lub xovtooj.
Dab tsi yog qhov nres codon hauv koj tus tub txib RNA?
A stop codon yog a trinucleotide sib lawv liag nyob rau hauv ib tug tub txib RNA (mRNA) molecule uas taw qhia ib tug nres rau protein synthesis. … Ntawm 64 qhov sib xyaw ua ke ntawm peb lub hauv paus, 61 qhia meej cov amino acid, thaum peb qhov kev sib txuas ntxiv yog nres codons.
4 codons rau RNA yog dab tsi?
