Document Summary
Alive : chemistry -> biology that when replication occurs. 500 my difference between habitable and life life forms very quickly, which tells us that this phenomenon was rapid. Dna unites all the living organisms today the fossil records do not really showcase the rna hypothesis: so basically dna took over rna"s job real quick. Showed a video on the oldest fossils natgeo. Life requires chemicals capable of: storing information, replicating info and transmitting it (catalysis and heredity, modifiable. Some common biopolymers that could have participated in the formation of early life include: Proteins: amino acid diversity, and catalysis, unlikely that it was the primary chemical in the formation of life (not complex enough/ not stable enough) Dna is replicated by proteins and proteins are specified by dna : dna and proteins rely on one another, thus, the origin of life probably started from rna. It has the traits of diversity, storage and catalysis.
