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
There are 61 codons for amino acids, and each of them is "read" to specify a certain amino acid out of the 20 commonly found in proteins. One codon, AUG, specifies the amino acid …
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 …
Transcription and mRNA processing (article) | Khan Academy
These sequences are like a code, where groups of three bases (called codons) specify particular amino acids to build proteins. For example: A segment of DNA with the base sequence ATG …
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).
Stages of translation (article) | Khan Academy
In an mRNA, the instructions for building a polypeptide come in groups of three nucleotides called codons. Here are some key features of codons to keep in mind as we move forward:
O código genético (artigo) | Tradução | Khan Academy
O código genético liga grupos de nucleotídeos de um RNAm a aminoácidos de uma proteína. Códons de início, códons de parada, pauta de leitura.
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 …
DNA function & structure (with diagram) (article) | Khan Academy
If nucleotides are like letters, then codons are like words. Unlike English, where we use 26 letters to make words of all different lengths and meanings, your cells use the four DNA nucleotide …
The trp operon (article) | Khan Academy
If there is little tryptophan, the ribosome will stall at the Trp codons (waiting for a Trp-carrying tRNA) and will be slow to finish translation of the leader. Why does it matter if the ribosome …
