What is the best way to describe our current understanding of the one-gene/one-polypeptide hypothesis

It applies to prokaryotes but not to eukaryotes.

Explanation:

one-gene/one-polypeptide hypothesis is based on the idea that there is a structurally complex gene whereby each gene encodes a single polypeptide, that either operates on its own or under a relatively more complex protein.

However, based on the existing findings and research, the one-gene/one-polypeptide hypothesis "applies to prokaryotes but not to eukaryotes."

This is because one gene/one-polypeptide cannot be used to explain different spliced versions found in several eukaryote organisms

the most logical answer would be a

brain development. a child's brain undergoes an amazing period of development from birth to three—producing more than a million neural connections each second. the development of the brain is influenced by many factors, including a child's relationships, experiences and environment.
