Question

question 10 of 10
which best describes a difference between transcription and dna replication?
a. only dna replication happens in the nucleus.
b. dna replication produces mrna.
c. transcription does not use dna.
d. they use different nucleotide bases.

Explanation:

• Option A: Both DNA replication and transcription occur in the nucleus (in eukaryotes). So, this option is incorrect.
• Option B: DNA replication produces DNA, not mRNA. Transcription produces mRNA. So, this option is incorrect.
• Option C: Transcription uses DNA as a template. So, this option is incorrect.
• Option D: DNA replication uses thymine (T) as a nucleotide base. Transcription uses uracil (U) instead of thymine (T) (since it produces RNA). So, they use different nucleotide bases, and this option is correct.

Answer:

D. They use different nucleotide bases.
