Summarize the experiments of griffith and avery that indicates that dna is the genetic material

The Griffith was conducted in 1928 which was first major experience for DNA. It studied the strains of bacteria of the pneumonia it was found to have R and S strain and genetic transfer. In 1944 Avery conducted  an experience with the R and S strain found the maromolecules to understand what causes a diease tto carry the nucleic acid

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
