How does a template strand of DNA code for an aminó acid? (Can you list all the steps?)

The template strand is the antisense strand or non-coding strand with polarity in the direction of 3' to 5' end which codes for the primary RNA molecule.

The template strand codes for the proteins through transcription and translation. The transcription creates a copy of the sense strand in the form of RNA as RNA polymerase binds the promoter and adds nucleotides in 3' to 5' direction.

The mRNA molecule formed as a result of transcription contains code in the form of codon or triplets of nitrogenous bases which are read by the ribosomes and specific amino acids are added to the growing polypeptide chain via tRNA molecule.

Thus, a template strand codes for amino acids.
