The Miller and Urey experiment simulated conditions thought to be present on early Earth to test the origin of life. Using a closed system of flasks and tubes, water vapor was mixed with a variety of different gases to simulate an atmosphere that did not contain oxygen. The mixture was then exposed to an electrical discharge and allowed to cool. After a period of time, the mixture was analyzed and found to contain trace amino acids. The Miller and Urey experiment is shown.
Which is a significant finding of this experiment regarding the origin of life on Earth?
Specific nitrogen bases will always pair together when a DNA molecule is formed. Because of this, which of the following will always be true of a DNA molecule?
Which of the following diagrams best represents DNA replication?
