Answer 2

`\boxed {\tt Uracil}`

Step-by-step explanation:

The nitrogenous bases in deoxyribonucleic acid, or DNA are:

• Thymine (T)
• Cytosine (C)
• Adenine (A)
• Guanine (G)

The nitrogenous bases in ribonucleic acid, or RNA are:

• Uracil (U)
• Cytosine (C)
• Adenine (A)
• Guanine (G)

When we compare the lists, we notice that RNA contains uracil instead of the thymine in DNA. Therefore, the correct answer is B. Uracil
