CHE SIGNIFICA CODON IN INGLESE
Codice genetico
Il codice genetico è l'insieme delle regole con le quali le informazioni codificate nel materiale genetico sono tradotte in proteine da cellule viventi. La decodifica biologica è compiuta dal ribosoma, che collega gli aminoacidi in un ordine specificato da mRNA, utilizzando molecole di RNA di trasferimento per trasportare aminoacidi e per leggere i tre nucleotidi mRNA alla volta. Il codice genetico è molto simile a tutti gli organismi e può essere espresso in un semplice tavolo con 64 voci. Il codice definisce come le sequenze di questi tripletti nucleotidi, chiamati codoni, specificano quale aminoacido verrà aggiunto successivamente durante la sintesi proteica. Con alcune eccezioni, un codone a tre nucleotidi in una sequenza di acido nucleico specifica un singolo amminoacido. Poiché la stragrande maggioranza dei geni è codificata con lo stesso codice, questo particolare codice è spesso definito come il codice genetico canonico o standard o semplicemente il codice genetico, anche se in realtà alcuni codici varianti sono stati evoluti. Ad esempio, la sintesi proteica nei mitocondri umani si basa su un codice genetico che si differenzia dal codice genetico standard.
definizione di codon nel dizionario inglese
La definizione di codone nel dizionario è un'unità che consiste di tre basi adiacenti su una molecola di DNA e che determina la posizione di uno specifico amminoacido in una molecola proteica durante la sintesi proteica.
