The Four Nitrogenous Bases of RNA are Abbreviated As

Question

The four nitrogenous bases of RNA are abbreviated as
A) A,G,C,and T.
B) A,G,T,and N.
C) G,C,U,and N.
D) A,G,U,and T.
E) A,G,C,and U.

Accepted Answer

The four nitrogenous bases of RNA are adenine (A), guanine (G), cytosine (C), and uracil (U). Since RNA does not contain thymine (T) like DNA, choice A is not correct. Choice B includes the letter N, which is not a nitrogenous base, so it is also not correct. Choice C includes the letter N and does not include uracil (U), so it is also not correct. Therefore, the correct answer is E, which lists the four nitrogenous bases of RNA: A, G, C, and U.
