Final answer:
RNA differs from DNA because it has a different sugar (ribose instead of deoxyribose), a different base (uracil instead of thymine), and a different function in protein synthesis rather than genetic information storage. The correct options are 1,2,3.
Step-by-step explanation:
RNA differs from DNA in several ways. The correct checks that apply are as follows:
- The sugar is different: RNA contains the 5-carbon sugar ribose, whereas DNA contains deoxyribose.
- One of the bases is different: RNA uses the base uracil (U) in place of DNA's thymine (T).
- The function is different: RNA's primary role is to manifest the genetic code into proteins, while DNA stores genetic information.
The phosphate group, however, is not different between DNA and RNA; both contain a phosphate group in their nucleotide structure. The correct options are 1,2,3.
