# Cod onThis challenge uses the Codons. A codon is a sequence of 3 letters, A, U, C or G.In genetics, there are two types of massages: DNA and RNA. We can see that it is RNA by the presence of uracil (U)
We can translate to nitrogenous bases using this table :

We also need the entire name of the nitrogenous bases :
Ala: Alanine   Arg: Arginine  Asn: Asparagine  Asp: Aspartic acid  
Cys: Cysteine  Glu: Glutamic acid  Gln: Glutamine  Gly: Glycine  
His: Histidine  Ile: Isoleucine  Leu: Leucine   Lys: Lysine  
Met: Methionine  Phe: Phenylalanine  Pro: Proline   Ser: Serine
Thr: Threonine   Trp: Tryptophan  Tyr: Tyrosine  Val: Valine
After translation, it give us :``` AUG ->	Methionine	CAA	->	Glutamine	GGU	->	Glycine		CUC	->	Leucine		UUG	->	Leucine	ACC	->	ThreonineCAG	->	GlutamineUGG	->	TryptophanAUA	->	Isoleucine	CUA	->	Leucine		AAU	->	AsparagineGCC	->	Alanine		UGG	->	TryptophanAAG	->	Lysine	GUA	->	Valine	GCA	->	Alanine	UAC	->	TyrosineUAG	->	END```
The first codon, the Methionine, is a "start" codon, it's always at the beginning of a RNA portion.now, lets apply the key `Key: 6, 3, 4, 3, 1, 9, 8, 3, 3, 2, 7, 4, 1, 2, 4, 1`, ingnoring the first and the last codon, "start" and "stop", and take the X letter of the name of the nitrogenous bases :``` AUG	    ->	Methionine	->	STARTCAA6	->	Glutamine	->	MGGU3	->	Glycine		->	YCUC4	->	Leucine		->	CUUG3	->	Leucine		->	UACC1	->	Threonine	->	TCAG9	->	Glutamine	->	EUGG8	->	Tryptophan	->	HAUA3	->	Isoleucine	->	OCUA3	->	Leucine		->	UAAU2	->	Asparagine	->	SGCC7	->	Alanine		->	EUGG4	->	Tryptophan	->	PAAG1	->	Lysine		->	LGUA2	->	Valine		->	AGCA4	->	Alanine		->	NUAC1	->	Tyrosine	->	TUAG	    ->	END		    ->	END```
It gives us the following flag : `rtcp{my_cute_houseplant}`
PS : Yes, Daphne, you were a cute houseplant
