A science researcher has developed a computer model of the process of DNA replication in a eukaryotic cell. The model includes the following
sequence of bases in one strand of the DNA molecule.

The researcher wants to revise the model to show the transcription of DNA to form mRNA
Which of these revisions to the model would be most useful for the researcher to include?
A
Replace thymine (T) with uracil (U) in the DNA molecule.
B. Keep the two strands of the DNA molecule joined together.
C. Identify promoter and "stop" regions on the DNA molecule.
D. Divide the DNA molecule into pieces that are 40 to 50 bases long
