Chapter 23.1, Problem 2CYP
Summary Introduction
To analyze:
The miller experiment about the formation of the first organic molecule
Introduction:
The miller experiment is a successful experiment fundamentally that the earth’s primitive atmosphere was able toproducing the building blocks of life from inorganic materials. The situation that exists in the earth’s primitive atmosphere was sufficient to forms organic molecules such as amino acid

Understand the importance of the Miller-Urey experiments that recreated the conditions present in early earth and caused organic molecules to form spontaneously.
Which of the following was the least likely objective of the Urey-Miller experiment?
Group of answer choices
To demonstrate that oxygen can be produced by plants.
To recreate the conditions of the Earth before life existed and produce the molecules necessary for life from primordial inorganic matter (water, methane, ammonia, and carbon dioxide).
To build a case (though not necessarily prove) that life can originate from nonliving matter through natural means.
To demonstrate that organic molecules like amino acids (building blocks of protein) and nucleotide bases (building blocks of DNA) do not necessarily originate only from living matter.
To demonstrate that lightning may have been the essential energy source (early in Earth's evolution) in the production of molecules essential for life.
Discuss the hypothesis of Alexander Oparin and John B.S. Haldane about how living matter came to be.
