what is the language of the gene?
A, T, C AND G however if RNA U instead of T.

what is the coding strand?
one side of the DNA ladder that acts as a code for making proteins.

process of a genetic code in a cell...
1) the DNA molecule unzips down the middle. 2)the bases are exposed along the coding strand 3) three bases in a coding strand is called a triplet. 4) the triplet decides where one amino acid is to be put into the protein.

transcription process...
the relevant gene in the DNA in the nucleus is copied into a molecule of RNA called mRNA or messenger RNA. The enzyme RNA polymerase does this. The RNA polymerase joins to the DNA at a special order of bases called the PROMOTER REGION.
