Document Summary
Dna is the genetic material - cellular life only. Nuclein later on became dna, phosphorus rich. Doesn"t mean that genes are made up of dna. Nucleotides are joined by the phosphodiester bonds, won"t find phosphorus in protein. ** don"t need to know dates, know his name. Started the thinking into how to prove its dna. Working with bacteria double stranded dna, circular, haploid. This organism is not a pathogen for mice, but in humans it causes pneumonia. 1920"s no vaccine, caused many deaths in children. Humans carry in upper respiratory tract, only a problem when it gets into your lungs or. If you inject enough bacteria into the mice they will die. Capsule - carbohydrate capsule (smooth), mutants in the body won"t survive, but will in the lab. Growth advantage over the smooth form don"t have to spend resources and energy into making the capsule (rough)
