Document Summary
Replicates faithfully: be able to be replicated exactly as how it is which provides stability. Makes it so it is hereditary and makes it so the exact same gene is continued on; preservation of the information. Has the ability to mutate, which ironically is the opposite of the second characteristic which is keeping it the same. You need that variability for the organism to be able to adapt to its environment. The 2 stranded shape relates to the storage of information and the faithful replication. How do these functions of dna relate to the physical structure. What are dna sequences related to dna info, the importance. Miescher; used salmon sperm because that was what was readily available to isolate dna. Avery, macleod, mccarty; showed pathogenic strains are transferred, showed that something in dna can transfer. Chargaff; reportated the qualities of a+t and c+g in dna were the same value.
