Have you ever written a secret message to one of your friends? If so, you may have used a code to keep the message hidden. For instance, you may have replaced the letters of the word with numbers or symbols, following a particular set of rules. In order for your friend to understand the message, they would need to know the code and apply the same set of rules, in reverse, to decode it.
Introducing, Genetic Code
But before that, what is Genetic Code anyway? – The genetic code by which DNA stores the genetic information consists of "codons" of three nucleotides. The genetic code is a set of three-letter combinations of nucleotides called codons, each of which corresponds to a specific amino acid or stop signal.
I won't go much deeper how or when did Genetic Code occurs. Our main objective is how is the Genetic Code used as an Encrypted message. Let's start.
First, we need a Genetic Table as reference but if you memorize the sequence, no problem for that.
(Please refer to the first photo)
For free data here it is: UUU- Phe UCU- Ser UUC- Phe UCC- Ser UUA- Leu UCA-Ser UUG- Leu UCG- Ser CUU- Leu CCU- Pro CUC-Leu CCC- Pro CUA-Leu CCA- Pro CUG-Leu CCG- Pro AUU- Ile ACU-Thr AUC- Ile ACC-Thr AUA- Ile ACA- Thr AUG- Met ACG-Thr GUU- Val GCU- Ala GUC- Val GCC- Ala GUA- Val GCA- Ala GUG- Val GCG- Ala UAU- Tyr UGU- Cys UAC- Tyr UGC- Cys UAA- Stop UGA- Stop UAG- Stop UGG- Trp CAU- His CGU- Arg CAC- His CGC- Arg CAA- Gin CGA- Arg CAG- Gin CGG- Arg AAU- Asn AGU- Ser AAC- Asn AGC- Ser AAA- Lys AGA- Arg AAU- Lys AGU- Arg GAU- Asp GGU- Gly GAC- Asp GGC- Gly GAA- Glu GGA- Gly GAG- Glu GGG-Gly
Second. We need the a table for corresponding letters in every amino acids.
(Please refer to second photo)
For free data. Here it is. [Amino acid] = Letter Alanine (Ala)= A Cysteine (Cys)=C Aspartic acid (Asp)=D Glutamic acid (Glu)=E Phenylalanine (Phe)=F Glycine (Gly)=G Histidine (His)=H Isoleucine (Ile)=I/J Lysine (Lys)=K Leucine (Leu)=L Methionine (Met)=M Asparagine (Asn)=N Proline (Pro)=P Glutamine (Gln)=Q Arginine (Arg)=R Serine (Ser)=S Threonine (Thr)=T Valine (Val)=V Tryptophan (Trp)=W Tyrosine (Tyr)=Y Stop codon : UAG=O UGA=U
*In this code, B,X,Z is not available*
So now let's have an example. "FAREWELL"
• To convert that to Genetic Code, look for the amino acid that corresponds the letter then use the codon.
F or Phenylalanine has 2 codons so use any from the 2 codon as replacement or decryption. (This goes to other letters with more than one codon.
UUC/GCA/CGA/GAA/UGG/GAG/CUC/CUA// In this example, I used UUC as decryption but you can use UUU. It's up to you which will you use. Same as "E" and "L" in the example.
• In the division of letters and words. I used the rule in morse code, but you can use any symbols as division. Either, "<>" , "|" , "()" , "[]" , "{}"
It's up to you.
So that's it. Hope you understand and enjoy it. Comment down for further queries, violent reactions and etc.
