Which of the following is a nitrogen base found ONLY in RNA?
a. Thymine
b. Uracil
c. Deoxyribose
d. Adenine
e. All of the above except b.
Answer: b. Uracil
The nitrogen base named here as Guanine falls under RNA more known as Ribonucleic acid. There is thymine. The first is the nitrogenous bases and this includes adenine, guanine, and cytosine which are in D. N. A and R. N. A. Next is the Carbohydrate compounds; these include the ribose sugar in RNA and the deoxyribose sugar in DNA. Another independent practice which has been noted is that whereas there is the RNA a molecule with uracil; there is also the DNA a molecule with thymine. It is of great help during the related activity that takes place in the cell including the synthesis of proteins and genetic material to mention but a few because it assists in the distinction of RNA and DNA during transcriptions and translations.
