DNA: The Heredity Material and Different Experiments to Prove that!!

What is DNA?
What is a Gene?
What is Mutation?
How it was determined that DNA is heredity material?
DNA as heredity material
Genes—the hereditary “factors” described by Mendel—were known to be associated with specific traits, but their physical nature was not understood.
Mutations were known to alter gene function, but precisely what a mutation is also was not understood.
The one-gene–one-polypeptide hypothesis postulated that genes control the structure of proteins and other polypeptides
Genes were known to be carried on chromosomes.
The chromosomes were found to consist of DNA and protein.
The results of a series of experiments beginning in the 1920s revealed that DNA is the genetic material.
Frederick Griffith experiments
Frederick Griffith performed experiments in 1928 on the bacterium Streptococcus pneumonia
Avery, Macleod and McCarty Experiments
Avery, Macleod and McCarty Experiments on mice
Hershey and Chase experiments
Alfred Hershey and Martha Chase provided additional evidence in 1952 that DNA is the genetic material or transforming principle
They used phage T2, a virus that infects bacteria DNA
