The resulting mRNA is a single-stranded copy of the gene, which next must be translated into a protein molecule. During translation, which is the second major step in gene expression, the mRNA is read according to the genetic code, which relates the DNA sequence to the amino acid sequence in proteins (Figure 2).
  Transcription is the synthesis of RNA under the direction of DNA. The type of RNA used during transcription is the messenger RNA. The mRNA carries a genetic message from â¦ the DNA to the protein-synthesizing machinery of the cell.Then, translation is the actual synthesis of a polypeptide, which occurs under the direction of mRNA.denine always pairs with th â¦ ymine and guanine always pairs with cytosine. Alternating sugar and phosphate parts are along the sides of DNA and genes, nitrogen bases and nucleotides is basically the code of DNA.
