Questions: For a specific gene, transcription takes place Only on the coding strand On both the template and coding strands Only on the template strand

The answer is the third one: Only on the template strand.

Explanation for each option:

1. Only on the coding strand: This is incorrect. Transcription occurs on the template strand, not the coding strand. The coding strand has the same sequence as the RNA transcript (except for thymine being replaced by uracil), but it is not the strand used by RNA polymerase to synthesize RNA.

2. On both the template and coding strands: This is incorrect. Transcription occurs only on the template strand. The coding strand is not used for transcription; it serves as a reference for the sequence of the RNA.

3. Only on the template strand: This is correct. During transcription, RNA polymerase binds to the template strand of DNA and synthesizes a complementary RNA strand. The template strand is used to guide the synthesis of the RNA molecule.

In summary, transcription takes place only on the template strand of DNA.
