HOL 1 Flashcards
Germ Hypothesis
Preexisting microorganisms present in the air can contaminate the nutrient broth
Spontaneous Generation Hypothesis
Living organisms can be generated spontaneously from nonliving organic molecules in broth
What did Louis Pasteur Disprove
Spontaneous generation Hypothesis
Oparin-Haldane hypothesis
life arose gradually from inorganic molecules, with “building blocks” like amino acids forming first and then combining to make complex polymers
Steps of Oparin-Haldane
Organic molecules including amino acids and nucleotides were synthesized first
Then, these building blocks were assembled into polymers of proteins and nucleic acids in the prebiotic soup
The polymers formed a self-replicating organism that fed on the existing organic molecules
What does the concept of protocell refer to
compartment where replication of the primitive genetic material took place and where primitive catalysts gave rise to products that accumulated locally for the benefit of the replicating cellular entity.
