which type of sugar is found in rna?
fructose
deoxyribose
glucose
ribose

Explanation:

1. In eukaryotic cells, RNA is synthesized in the nucleus (transcription) and then moves to the cytoplasm for functions like translation. So it is found in both nucleus and cytoplasm.
2. RNA is usually single - stranded. DNA has a double - helix structure.
3. RNA stands for ribonucleic acid. The sugar in RNA is ribose. Deoxyribose is in DNA, fructose is a simple sugar (monosaccharide) not in nucleic acids, and glucose is also a simple sugar not in nucleic acids.

Answer:

1. nucleus and cytoplasm
2. False
3. ribose
