What are the nitrogenous bases in RNA?

Nitrogenous base: A molecule that contains nitrogen and has the chemical properties of a base. The nitrogenous bases in DNA are adenine (A), guanine (G), thymine (T), and cytosine (C). The nitrogenous bases in RNA are the same, with one exception: adenine (A), guanine (G), uracil (U), and cytosine (C).

Consequently, which bases are found in RNA?

Cytosine (C) and thymine (T) are the smaller pyrimidines. RNA also contains four different bases. Three of these are the same as in DNA: adenine, guanine, and cytosine. RNA contains uracil (U) instead of thymine (T).

What are the four types of nitrogenous bases found in RNA?

b. a nitrogenous base (def). There are four nitrogenous bases found in RNA: adenine, guanine, cytosine, or uracil. Adenine and guanine are known as purine (def) bases while cytosine and uracil are known as pyrimidine bases (def) (see Fig. 3).

What bases go together in RNA?

The base pairing of guanine (G) and cytosine (C) is just the same in DNA and RNA. So in RNA the important base pairs are: adenine (A) pairs with uracil (U); guanine (G) pairs with cytosine (C).
