Question
Select the name of a compound that is present in both DNA and RNA.
- Thymine
- Uracil
- Ribose
- Cytosine
Solution
To answer this question, we will analyze the involvement of each option in DNA and RNA.
- Thymine: This is a nitrogenous base found only in DNA, not in RNA.
- Uracil: This nitrogenous base is unique to RNA and replaces thymine in RNA. It is not present in DNA.
- Ribose: This is the sugar component of RNA, while DNA contains deoxyribose. Therefore, ribose is not present in DNA.
- Cytosine: This is a nitrogenous base that is present in both DNA and RNA.
Summary
Among the options provided, Cytosine is the only compound that is present in both DNA and RNA.
