Biogenic Worlds: From atmospheric HCN production to the building blocks of RNA in warm little ponds
Event Start:
2021-06-07T15:00:00
Event End:
2021-06-07T16:00:00
Event Information:
What is the origin of the building blocks of life on early Earth? Is it necessary that they were delivered by meteorites or interplanetary dust? Or was early Earth "biogenic," and could produce key biomolecules on its own? An atmosphere rich in HCN is a distinguishing feature of what we term biogenic worlds. HCN is a key species produced in Miller-Urey electric discharge experiments simulating lightning-based chemistry in the primordial atmosphere. HCN reacts in water to form nucleobases and ribose, the building blocks of RNA, and amino acids, the building blocks of proteins.
