Question

Given below are some biological terms. Write a single collecting term for each group.

Adenine, thymine, cytosine, guanine

Answer 1

1. Nitrogenous bases are nitrogen-containing compounds that form nucleosides.
2. They are of two kinds: purine and pyrimidine
3. Purine are the 9-membered and double-ringed structure that includes adenine (A) and guanine(G).
4. Pyrimidine are a 6-membered and single-ringed structure that includes cytosine (C) and thymine (T).
5. Each DNA molecule consists of four nitrogen-containing nucleobases: Adenine (A), Cytosine (C), Guanine (G) and thymine (T).
6. Nucleosides are components of nucleotides.
7. Nucleotides are building blocks of nucleic acids.

Conclusion: So, the single collecting term for each group of Adenine, thymine, cytosine, guanine is: Nucleobases
