Identifying Nucleic Acids

APBIO-XKVVLK

A student is given two samples of nucleotides. One sample contains DNA nucleotides and the other sample contains RNA nucleotides, but the two samples have not been labeled.

Which of the following information would assist the student in identifying which sample contained the DNA nucleotides versus the RNA nucleotides?

A

The sugar in DNA nucleotides contains six carbon atoms, and the sugar in an RNA molecule contains five carbon atoms.

B

The sugar in DNA nucleotides is an aldehyde sugar, and the sugar in RNA nucleotides is a ketone sugar.

C

The sugar in DNA nucleotides contains one less oxygen atom than the sugar in RNA nucleotides.

D

The sugar in DNA nucleotides is in the alpha configuration, and the sugar in RNA nucleotides is in the beta configuration.
