Questions: What four nitrogenous bases are found in RNA?
Transcript text: What four nitrogenous bases are found in RNA?
Solution
The answer is the second one: adenine, uracil, guanine, cytosine.
Explanation for each option:
Adenine, thymine, guanine, cytosine: This set of nitrogenous bases is found in DNA, not RNA. In DNA, thymine pairs with adenine.
Adenine, uracil, guanine, cytosine: This is the correct set of nitrogenous bases found in RNA. In RNA, uracil replaces thymine and pairs with adenine.
Glucose, fructose, maltose, lactose: These are not nitrogenous bases; they are types of sugars. Glucose and fructose are monosaccharides, while maltose and lactose are disaccharides.
In summary, the nitrogenous bases found in RNA are adenine, uracil, guanine, and cytosine.
