Assuming that transcription and translation both proceed from left to right, the correct orientation of the DNA template, the RNA transcript, and the protein product is as follows:

  1. DNA Template: The DNA template is read in the 3’ to 5’ direction. The template strand acts as a guide for RNA synthesis during transcription. It is complementary to the RNA transcript and runs in the opposite direction.

  2. RNA Transcript: The RNA transcript is synthesized in the 5’ to 3’ direction, which is the same direction as the leading strand of the DNA template. The RNA transcript is complementary to the template strand of DNA and contains the same sequence as the non-template strand (except for the replacement of thymine with uracil in RNA).

  3. Protein Product: The protein product is synthesized in the 5’ to 3’ direction, just like the RNA transcript. During translation, the ribosome reads the mRNA (which is the RNA transcript) in codons (groups of three nucleotides) and assembles the corresponding amino acids into a polypeptide chain. The protein product is synthesized from the N-terminus (start) to the C-terminus (end) in the 5’ to 3’ direction.

In summary, assuming left-to-right orientation for transcription and translation, the DNA template is read in the 3’ to 5’ direction, the RNA transcript is synthesized in the 5’ to 3’ direction, and the protein product is also synthesized in the 5’ to 3’ direction.
