The DNA changes that are described in Henry's story are changes to the coding strands of the CYP2C9 genes. What is the function of the coding strand and how does it differ from the function of the template strand of Henry's CYP2C9 gene?

Answer: the coding strand of Henry CYP2C9 aids in the determination of the precise/correct nucleotide sequence of the RNA strand produced after transcription

Explanation: The template strand functions in the production of the RNA strand during transcription ie the RNA strand is complementary to the template strand. RNA produced runs from the 5' to 3' direction. The coding strand differs from the template strand in that it is the strand that contains the exact nucleotide sequence as the RNA strand but differs in that the RNA is replaced with uracil instead of thymine and it also runs in the 5' to 3' direction.
