He performed an experiment that explain what occurred on primitive earth billions of years ago. He sent an electrical charge through a flask of chemical solution of methane, ammonia, hydrogen and water. This created organic compounds including amino acids

Meteorologists classify tropical cyclones using a measurement of sustained winds within the low-pressure system. How do meteorologists define a "sustained wind"?
it is a 1-minute averaged measure of the hurricane's maximum winds.

Answer:
The purine ring is built onto ribose-5-phosphate of PRPP for its de-novo nucleotide biosynthesis, while the ring structure of the pyrimidine bases are synthesized separately and then coupled to ribose-5-phosphate via the C-N glycosidic bond.
Explanation:
In the de novo synthesis of nucleotides, their metabolic precursors such as aminoacids, ribose-5-phosphate, CO₂ and NH₃ are used as starting materials.
In purine nucleotide synthesis, the ring structure is built up on ribose-5-phosphate of PRPP by addition of one or a few atoms one at a time starting with the amino group donated by glutamine until the first intermediate inosinate is synthesized.
In pyrimidine ring synthesis, orotate is first synthesized from carbamoyl phosphate and aspartate, and then is attached to ribose-5-phosphate of PRPP, before it is then converted to the common pyrimidine nucleotides starting from uridylate.
