- The genetic code codon table (article) | Khan Academy
To see how the codon table works, let's walk through an example Suppose that we are interested in the codon CAG and want to know which amino acid it specifies

- The genetic code (article) | Khan Academy
The codon table may look kind of intimidating at first Fortunately, it's organized in a logical way, and it's not too hard to use once you understand this organization
- Impact of mutations on translation into amino acids
Now, what are we coding for? Well, when we transcribe to RNA, this will be A-A-G-U-C-G-A-U-A-A-A, and now this first codon still codes for lysine, we've seen that multiple times But, what about this second codon? This second codon over here, UCG UCG, that's serine, we got a different amino acid

It's this little squiggly line, matches up the the appropriate Codon, and then puts that Amino Acid in place You also have things like Ribosomal RNA that make up the structure of the actual Ribosomes

Test your knowledge of the different kinds of mutations!
- Intro to gene expression (central dogma) - Khan Academy
During translation, the nucleotides of the mRNA are read in groups of three called codons Each codon specifies a particular amino acid or a stop signal This set of relationships is known as the genetic code
- tRNAs and ribosomes (article) | Translation | Khan Academy
The ribosome moves forward on the mRNA, codon by codon, as it is read and translated into a polypeptide (protein chain) Then, once translation is finished, the two pieces come apart again and can be reused
