What are the building blocks of nucleic acids? List the two types?

I was doing my AP biology assignment and came across this question. I thought the answer was "nucleotide" but it says two types?
There are two types?
Help! im so confused

I think they are two different questions. The second one is not list the two types of building blocks, it should be list the two types of nucleic acids.
So to answer your question:
Building blocks of nucleic acid: Pentose sugar, nitrogenous base (purine or pyrimidine), phosphate group.
Two types of nucleic acid: Deoxyribo nucleic acid (DNA) and Ribonucleic acid (RNA).
I think they might be fishing for DNA and RNA, both nucleic acids.

Erm…I know for DNA (deoxyribonucleic acid) there’s a base, a phosphate, and a…what, sugar or something? Not sure if that helps at all…:/
Deoxyribose, Ribose, ATGCU, Phophates
RNA and DNA possibly. I love science, but biology wasn’t my strongest point. =\
purine and pyrimidine
Purine: Adenine and Guanine
Pyrimidine: Thymine (or Uracil for RNA) and Cytosine
