Question

Guanine and adenine belong to __________ and Thymine and Uracil are __________ bases.

Answer 1

Answer:

Thymine and uracil are identical except that T includes a methyl group that U lacks. Adenine and guanine have a fused-ring skeletal structure derived of purine, hence they are called purine bases.

Answer 2

Answer:

Guanine and adenine belong to Purine and Thymine and Uracil are Pyrimidine bases.

Explanation:

Nucleic acid is carries the genetic material of all organisms on the planet without exception.

There are two major types of Nucleic acids i.e.

• DNA - Deoxyribonucleic acid
• RNA - Ribonucleic acid

DNA is a double stranded double helix structure. It is made up of nucleotides which has a sugar group and a phosphate group and a nitrogenous bases.

The nitrogenous bases are of two types namely

1. Purines:

• Heterocyclic aromatic organic compound
• Composed of a pyrimidine ring fused with imidazole ring.
• Guanine and adenine are purine bases.

2. Pyrimidine:

• Heterocyclic aromatic organic compound
• Composed of carbon and hydrogen.
• Thymine, Cytosine and Uracil are pyrimidine bases.
