Transcript text: Uracil is found in most RNA, while $\qquad$ is found in most DNA.
5-methyluracil
3-methyluracil
3-methylguanosine
5-methylguanosine
Solution
The answer is the first one: 5-methyluracil.
Explanation:
5-methyluracil: This is another name for thymine, which is found in most DNA. Thymine is the base that pairs with adenine in DNA, replacing uracil, which is found in RNA.
3-methyluracil: This is not a standard base found in DNA.
3-methylguanosine: This is a modified form of guanosine, not typically found in DNA.
5-methylguanosine: This is also a modified form of guanosine, not typically found in DNA.
Summary: In DNA, thymine (5-methyluracil) is the base that corresponds to uracil in RNA.
