- 1Why is there diversity?Due to mutations in DNA
- 2DNA does what (3) things w/ info.?Replicate, store, express
- 3Genetic material allows for...?Variations via mutations
- 4In history, DNA was considered too___ while protein seemed more ___? Why?Simple; abundant; Since protein has 20 amino acids + DNA has 4 nucleotides
- 5Griffith's experiment w/ what proved what?(Dead S strain + live mutant R strain) = kills; DNA has a transforming principle that is heat resistant
- 6What experiment seen the fixing of nonfunctioning mutant alleles into function copies?Griffith
- 7What part of cell was used to pass on genetic info. According to who?The polysaccharide capsule. Griffith.
- 8Who demonstrated the transforming principle of DNA by repeating who's experiment?Avery + colleagues; Griffith
- 9What did Avery do to prove his theory?Destroy different components of a cell + found when DNA is destroyed mutant R strains doesn't change
- 10Who experimented w/ bacteriophages dipped in sulfur + phosphate?Hershey + Chase
- 11What did Hershey + Chase prove?That bacteriophages infect bacteria via inserting its DNA (not protein)
- 12What does DNA do inside infected bacteria making it hazardous?Directs viral reproduction
