Document Summary
2 general themes to genes at the molecular wi. 1 genetic fi of dna flow directly from its molecular structure. So knowing the structure of dna we can understand biochemical processes of genetics. 2 the genetic fi of dna depend on the proteins that is chemically inert read the sequence extracted nucleic material from human white blood cell. F meischer 1969 chemical analysis revealed that stainingrevealed that dna is found in chromosomes used schiff reagent which stains dna red its map component was dna chemical composition of dna. A t c g chromosomes contain more protein than dna that hold the dna backbone. F griffith 1928 used 2 strains of streptococcus pneumoniae. R cells could be transformed by genetic material rough r strain nonvirulent virulent from dead s cells. Avery macleod mccarthy 1944 provided evidence that dna is the transforming principle of s cells.
