Question

rna contains the bases a, c, u, and t.
a true
b false

Explanation:

RNA (ribonucleic acid) has four nitrogen - containing bases. The bases are adenine (A), cytosine (C), guanine (G), and uracil (U). DNA (deoxyribonucleic acid) has adenine (A), cytosine (C), guanine (G), and thymine (T). So the statement that RNA contains A, C, U, and T is wrong.

Answer:

B. FALSE
