Which of the following is NOT a difference between DNA and RNA synthesis?

• A. DNA synthesis is catalyzed by DNA polymerase, while RNA synthesis is catalyzed by RNA polymerase.
• B. DNA synthesis uses deoxyribonucleotides, while RNA synthesis uses ribonucleotides.
• C. DNA synthesis requires a primer, while RNA synthesis does not.
• D. DNA synthesis occurs in the nucleus, while RNA synthesis occurs in the cytoplasm.

Answer: (D)

Verified step by step guidance

1. Identify the key enzymes involved in DNA and RNA synthesis: DNA synthesis is catalyzed by DNA polymerase, and RNA synthesis is catalyzed by RNA polymerase.
2. Understand the types of nucleotides used in each process: DNA synthesis uses deoxyribonucleotides, whereas RNA synthesis uses ribonucleotides.
3. Recognize the requirement of a primer: DNA synthesis requires a primer to initiate the process, while RNA synthesis does not need a primer.
4. Clarify the location of synthesis: DNA synthesis occurs in the nucleus of eukaryotic cells, and RNA synthesis also occurs in the nucleus, not the cytoplasm.
5. Conclude by identifying the incorrect statement: The statement that DNA synthesis occurs in the nucleus while RNA synthesis occurs in the cytoplasm is incorrect, as both processes occur in the nucleus in eukaryotic cells.
