NUCLEIC ACIDS:

  • Nucleic acids are one of the biological molecules in nature that functions in the storage and transportation of genetic information.

  • The two nucleic acids are DNA and RNA. These two nucleic acids are different in their structure. They are both made up of three components namely: nitrogenous bases, phosphate group and pentose sugar.

  • However, RNA contains only uracil base (U) while DNA contains only thymine base (T).

  • Therefore, the true statement about the nitrogenous bases in RNA and DNA is: Uracil is found in RNA only. Thymine is found in DNA only.
