What is the difference between DNA transcription for DNA synthesis and DNA transcription for protein synthesis?
A. Transcription for DNA synthesis is rapidly followed by the process of translation.
B. Transcription for protein synthesis has "greater fidelity" than does transcription for DNA synthesis.
C. Transcription for protein synthesis occurs only in cells undergoing mitosis and transcription for DNA synthesis occurs in both dividing and nondividing cells.
D. Transcription for DNA synthesis occurs with both the "sense" and the "antisense" strands, whereas transcription for protein synthesis occurs with only the "sense" strand.
D
Transcription for both DNA synthesis and RNA synthesis uses many of the same enzymes and three of the four same bases. When transcription occurs for DNA synthesis, both strands (the sense and the antisense strands) of DNA are completely copied. For protein synthesis, only the strand that actually contains the gene (the sense strand) is copied. The entire strand isn't copied—only the area where the specific gene is located.
