The genetic code (article) | Khan Academy
As we saw above, the genetic code is based on triplets of nucleotides called codons, which specify individual amino acids in a polypeptide (or "stop" signals at its end).
The genetic code & codon table (article) | Khan Academy
The genetic code links groups of nucleotides in an mRNA to amino acids in a protein. Start codons, stop codons, reading frame.
Overview of translation (article) | Khan Academy
How the nucleotide sequence of an mRNA is translated into the amino acid sequence of a polypeptide (protein).
O código genético (artigo) | Khan Academy
Como a informação contida em uma cadeia de mRNA é decodificada para formar um polipeptídeo? Aprenda como grupos de três nucleotídeos, chamados códons, especificam os aminoácidos (bem …
mRNA code and translation (article) | Khan Academy
This article covers the foundational concepts of codons, anticodons, the wobble hypothesis, and the universal nature of the genetic code, with applications that are essential for MCAT preparation.
Stages of transcription: initiation, elongation & termination (article ...
An in-depth looks at how transcription works. Initiation (promoters), elongation, and termination.
Le code génétique (leçon) | Khan Academy
Il existe trois codons d’arrêt dans le code génétique : UAA, UAG et UGA. Contrairement aux codons d’initiation, les codons d'arrêt ne correspondent à aucun acide aminé. Ils agissent comme des …
Types of mutations and their notations (article) | Khan Academy
Frameshift Mutation: If the number of inserted or deleted nucleotides is not a multiple of three, it causes a shift in the reading frame, altering all downstream codons.
RNA and protein synthesis review (article) | Khan Academy
The genetic code is read in three-base words called codons. Each codon corresponds to a single amino acid (or signals the starting and stopping points of a sequence).
