- TL;DR Summary
- mRNA codon eventual matches to amino acids are straightforward. But in a DNA double helix, it seems that, for example, referring to a ACG DNA codon is referring not to the end result (amino acid) of the ACG in the strand on which the ACG is found but to the end result of the complementary TGC on the other strand. If not.... then I'm confused. More detail in main text.
I refer to the tables on https://en.wikipedia.org/wiki/DNA_and_RNA_codon_tables
In both the DNA and the RNA codon tables, ACG codes for threonine. But the transcription of the ACG from the DNA to the mRNA ends up with UGC (which would code for Cysteine). So should I assume that when the DNA table talks about the ACG coding for threonine, it is talking about the TGC on the complementary DNA strand which would transcribe to ACG on the mRNA (which would code for threonine as promised)?
If not, then what step am I missing? Thanks.
