Document Summary

Nucleic acid: codes for the information of life and are the intermediates for rna. Central dogma: 3 distinct compartments in regards to information transfer. Dna self replicated, molecule allows for it to correct normally. Rna disposable copy of dna; makes one copy while keeping the integrity of the original molecule intact. In 1985, there is the reversible arrow from rna to dna due to the discovery of hiv/aids (retrovirus discovery) Panspermia: came as a bacteria which arrived on an asteroid that crashed on to earth and set the stage for the constancy of life on the planet. Concept of rna world is the most known. There was the search for a molecule that has a length associated with a polymer and can self replicate. Rna molecule that can replicate itself, catalytic property that carries out a function. Rna world concept: rna world has rna molecules; instead of doing a function they make a protein instead.
