Purine Base of Nucleic Acids
Nucleic acids are the building blocks of life and are responsible for the storage and transmission of genetic information. They are made up of four different types of nitrogenous bases: adenine, guanine, cytosine, and thymine (in DNA) or uracil (in RNA).
Purine bases are one of the two types of nitrogenous bases found in nucleic acids. They are characterized by their double-ring structure and include adenine and guanine.
Answer:
The purine base of nucleic acids in the following is adenine.
Explanation:
- Cytosine: Cytosine is a pyrimidine base, characterized by its single-ring structure. It pairs with guanine in DNA and RNA.
- Thymine: Thymine is a pyrimidine base found only in DNA. It pairs with adenine through hydrogen bonding.
- Uracil: Uracil is a pyrimidine base found only in RNA. It pairs with adenine through hydrogen bonding.
- Adenine: Adenine is a purine base characterized by its double-ring structure. It pairs with thymine in DNA and uracil in RNA.
Therefore, the purine base of nucleic acids in the given options is adenine.
