Answer 1

Could you help me with this question as well? @aaronq

Answer 2

A. DNA and RNA use the same four bases.

no. DNA uses A,G,T,C; RNA uses A,G,U,C

B. DNA and RNA have identical structures.

no. DNA is double stranded, RNA is single stranded

C. DNA and RNA use the same sugar.

yes and no. if you wanna be technical they dont.

DNA uses deoxyribose, RNA uses ribose; they're the same 5C sugar but one is missing an oxygen atom.



D. DNA and RNA are made up of repeating nucleotides.

hmm, repeating nucleotides.. yes and no.

they're not necessarily the same nucleotide ("repeating"); it's a sequence of nucleotides.

Answer 3

i would go with D
