Which nitrogenous bases are found in RNA?
A
Adenine, uracil, cytosine, and guanine
B
Adenine, thymine, cytosine, and guanine
C
Uracil, thymine, cytosine, and guanine
D
Adenine, uracil, cytosine, and thymine
Verified step by step guidance1
Recall that nucleic acids are composed of nitrogenous bases paired with sugar and phosphate groups. DNA and RNA differ in one key nitrogenous base.
Identify the four nitrogenous bases found in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G).
Understand that RNA differs from DNA by having uracil (U) instead of thymine (T).
Therefore, the nitrogenous bases in RNA are adenine (A), uracil (U), cytosine (C), and guanine (G).
Confirm that the correct set of nitrogenous bases in RNA excludes thymine and includes uracil.
