Here's another article about how amino acids, specifically glycine, could have been formed by comet impacts with the atmosphere of a planet.

> One of the essential components for DNA.-I had seen this article. The work is well done although proof of glycine was not achieved. Analysis of the Murchison meteorite did reveal eight amino acids, but those eight are the only ones found in meteorites so far, and life here uses 20. I don't remember which eight but glycine is so simple, it should be one of the eight.
