What functional groups do uracil,guanine,cytosine, and tyrosine belong to.

Nucleobases

To determine the functional groups in uracil, guanine, cytosine, and tyrosine, we need to understand the basic functional groups present in these molecules.

Uracil is a nitrogenous base found in RNA and belongs to the pyrimidine family. It contains two functional groups: a carbonyl group (C=O) and an amino group (NH2).

Guanine is a nitrogenous base found in both DNA and RNA and belongs to the purine family. It contains four functional groups: two carbonyl groups (C=O), an amino group (NH2), and an imino group (=NH).

Cytosine is also a nitrogenous base found in both DNA and RNA, and it is a pyrimidine like uracil. It contains three functional groups: a carbonyl group (C=O), an amino group (NH2), and a keto group (C=O).

Tyrosine is an amino acid that is not a part of the nucleotide bases in DNA or RNA but is crucial in protein synthesis. It contains four functional groups: a phenol group (OH), an amino group (NH2), a carboxyl group (COOH), and a benzene ring.

In summary:

- Uracil: Carbonyl group (C=O) and amino group (NH2)
- Guanine: Two carbonyl groups (C=O), amino group (NH2), and imino group (=NH)
- Cytosine: Carbonyl group (C=O), amino group (NH2), and keto group (C=O)
- Tyrosine: Phenol group (OH), amino group (NH2), carboxyl group (COOH), and benzene ring
