Answer
Process X is called transcription. During transcription, the DNA double helix unwinds, and the strands separate. One strand serves as a template to synthesize mRNA, using RNA nucleotides that are complementary to the DNA strand. The mRNA then carries the genetic information from DNA to the ribosome for protein synthesis.
