Study notes for the main scientists that participated in the early discovery of DNA and the early studies about DNA

-Hershey and pursuance showed that deoxyribonucleic acid is the contagious material of phages -Hershey and chase after intend protein in a T2 phage with a radioactive tag         -Then they labelled deoxyribonucleic acid in a better batch of phage with a radioactive isotope         -Both batches of mark phages were allowed to infect separate batches of E.Coli bacterium         -Afterwards, distich sets of E. Coli.

were placed in separate blenders to shake loose every parts of the phages that remained outside the bacterial cells         -The mixtures were then place in separate centrifuges and spun around to agitate the bacterial cells to form a pellet at the croupe of the centrifuge         -The viruses and parts of viruses remained in the supported         -Hershey and Chase found that the radioactively labeled proteins were found in the supported which contained viral particles                  -Protein of the phage didnt destroy the bacteria         -Bacteria infected with tagged deoxyribonucleic acid contained radioactivity                  -Showed that DNA of the virus is injected into troops cell and cause the bacteria to make new viral DNA and proteins         -DNA is hereditary material -Griffith enforce two varieties of a bacterium         -One was righteous and other was unhealthful -Griffiths experiment         -He inject a pinch with a unhealthful strain and it died         -Then he injected a slip with a righteous strain and it lived         -Then he injected the filch with cell dust of commove killed unhealthful strain and it lived         -Then he killed the pathogenic bacteria with fire up and mixed the cell system with living bacteria of the innocuous strain and injected it into a abstract -The mouse died and he found that just about of the living cells were converted to the pathogenic form         -Experiment showed that some chemical pump caused the change of the living nonpathogenic substances into pathogenic substances         -Griffith called this change of the harmless DNA into... I know how challenging biology can be and I only got through it by outlining EVERYTHING. Hope this helps everyone who needs it.
