mRNA Encoder/Decoder
These scripts are made to encode text to mRNA codon sequences and visa-versa. Use it here.
Encode
This script translates the single letter name of amino acids to the corresponding RNA. You can translate all letters (upper and lower), all numbers, most symbols (excluding ` and forward slash)
Decode
This script translates mRNA into the single letter name for the corresponding amino acid. It has a maximum of 100 codons per run
