Tommie, nucleic acids are polymers whose building blocks are nucleotides. Nucleotides have 3 parts - a sugar, phosphate group, and a nitrogen containing base.
The sugar in DNA is deoxyribose and the sugar in RNA is ribose. Thus DNA is deoxyribonucleic acid and RNA is ribonucleic acid.
So the first part of your question is true and the last part of your question is false.
