What is the "chicken-and-egg" type problem we face when trying to decide which came first-proteins or nucleic acids?
A) proteins and nucleic acids probably looked very different before the origin of life
B) nucleic acids cannot replicate without proteins, and proteins cannot be made without nucleic acids
C) early proteins and nucleic acids were very similar to each other
D) proteins and nucleic acids are always present together at the same time

Question

Quizplus · Accepted Answer

The chicken-and-egg problem refers to the fact that both proteins and nucleic acids are necessary for life, but it is unclear which came first in the process of the origin of life. The question of which came first is difficult to answer because proteins are necessary for the catalysis of chemical reactions, including the replication of nucleic acids, while the synthesis of proteins requires information stored in nucleic acids. This problem creates a conundrum because it is unclear which came first or how either could have arisen without the other.
