Nucleic Acids
RNA differs from DNA in having:
Select the correct option:
Solution
Ribose sugar and uracil instead of thymine
There are three primary differences between RNA and DNA:
- Sugar: RNA contains D-Ribose (−OH at C2), while DNA contains 2-Deoxy-D-ribose (−H at C2).
- Bases: Both have Adenine, Guanine, and Cytosine. However, RNA has Uracil (U) whereas DNA has Thymine (T).
- Structure: RNA is generally single-stranded, whereas DNA exists as a double helix.
