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
