The step in protein synthesis where DNA is transcribed or "copied" into RNA is called transcription. During this process, a molecule called mRNA (messenger RNA) is synthesized using a DNA template. This mRNA carries the genetic information from the DNA to the ribosomes, where it will be translated into a polypeptide chain.

In this process, the DNA sequence is first recognized and "unzipped" by an enzyme called RNA polymerase. The RNA polymerase then uses one of the DNA strands as a template to synthesize a complementary RNA molecule. This process happens in the nucleus of eukaryotic cells or the cytoplasm of prokaryotic cells.

The resulting mRNA molecule contains codons, which are sequences of three nucleotides that specify a particular amino acid. Each codon corresponds to a specific anticodon on transfer RNA (tRNA) molecules, which are involved in the next step of protein synthesis called translation.

During translation, the mRNA molecule moves to the ribosomes, which are composed of ribosomal RNA (rRNA) and proteins. The ribosomes "read" the mRNA sequence and match each codon with its complementary anticodon on the tRNA molecules. This allows the correct amino acids to be brought to the ribosome and linked together to form a polypeptide chain. Eventually, this polypeptide chain will fold and undergo modifications to become a functional protein.
