Question

How does 2-azahypoxanthine, a fungal product that stimulates plant growth, differ from guanine?

Short answer

Nitrogen is a part of the ring structure of 2-azahypoxanthine in the place of a second carbon of the guanine.

Step-by-step solution

Guanine

One of the four major nucleobases found in the nucleic acids DNA and RNA, together with adenine, cytosine, and thymine, is guanine (symbol G or Gua) (uracil in RNA). Guanine and cytosine are paired together in DNA. Guanosine is the name of the guanine nucleoside.

Difference in the structure of 2-Azahypoxanthine and guanine

2-azahypoxanthine has nitrogen in its ring structure in place of the second carbon of guanine.
