The diagram shows a nucleic acid in the shape of a helix.
IRINA_888 [86]
Well, to determine the type of sugar that is present and serves to play an important role in the overall structure and function of this particular nucleic acid is by the fact that the strand is single stranded, and not double stranded as in DNA. The only other commonly known Nucleic acid that is single stranded is RNA. Another clue or hint that points us in the direction to state that this a polynucleotide stranded molecule of RNA, is by the presence of the nitrogenous base, Uracil. DNA in place has thymine, uracil is only found on RNA, and is complementary to thymine, if used in transcription. Basically all of this information simply points to RNA, and the sugar contained in RNA would be ribose.
