Question

According to Urey and Miller experiment life originated from non-living matters

• A. True
• B. False

Answer 1

The correct option is A

True

Urey and Miller experiment provides evidence for the origin of life from non living matter. The Primitive atmosphere of Earth was reducing and had high temperature, volcanic storms containing CH4, NH3, H2, etc. Urey and Miller created the same atmosphere and took the same compounds in a closed flask along with water vapour at 800ºC and created an electric discharge. They observed the formation of biomolecules such as amino acids, simple sugars, fats, etc. in the flask. They believed that these simple molecules formed complex molecules in the reducing environment of earth and that they were the precursors of life.
