4. 1 million years ago life began, according to hypothesis: no evidence how life began. A few centuries ago: people thought that new living things appeared all of the time. If the neck is later broken off, outside air can carry microorganisms into the broth. Tons of different shit, look up in book.

Vii. xray diffraction of dna maurice wilkin and rosaland franklin knew that dna formed a helix by the pattern. How is information in a gene transcribed into rna: start with dna, using the information to produce a new nucleotide rna, rna polymerase- protein, contained of amino acids. Translation: aka protein synthesis: requirements, ribosomes, rrna both small and large subunits, trna, mrna, amino acids, *requires energy peptone bond, 3 steps, initiation, elongation, termination.
