There are several key differences between DNA and RNA, the two main types of nucleic acid. Identify the statement below that correctly describes a difference between RNA and DNA? (a) DNA uses phosphate groups to link nucleotides together whereas RNA uses ketone groups.
(b) Adenine binds with the nitrogen base thymine in DNA while it binds with uracil in RNA.
(c) DNA uses ribose while RNA uses deoxyribose as the sugar in the molecule’s backbone.
(d) DNA is a single-stranded molecule whereas RNA is a double-stranded molecule in cells.
