Question

Quizplus · Accepted Answer

The nucleotide sequence of DNA contains the four bases, A (adenine), T (thymine), G (guanine), and C (cytosine).

Answer: A
 The nucleotide sequence of DNA is the same in all organisms of a species, which is the basis for the universal genetic code.

Answer: B 
 The nucleotide sequence of DNA contains information for transcription and mRNA processing, in addition to translation.

Answer: C 
 It is believed that RNA may have preceded DNA in evolution.

Answer: E
 Prebiotic chemistry experiments may produce simple organic compounds, but the nucleotide sequence of DNA is not likely to be produced in these experiments.
