Scientists’ understanding of the role and function of DNA has built up over time. How did the findings from Hershey and Chase’s
bacteriophage experiments likely influence the Meselson-Stahl experiment, and how might Meselson and Stahl’s results help scientists understand how damaged DNA can be inherited by future generations?
Hershey & Chase concluded. after the experiment that the genetic material that is passed from virus to the bacteria is not the protein coat but DNA. It proves the DNA is the genetic material and not the protein.
After labelling the Phage DNA and protein, Hershey and Chase performed a series of experiments like infection, blending and centrifugation. Hershey and Chase gave full evidence of the DNA being a genetic material by their experiments. To perform the experiment, Hershey and Chase have taken T-2 bacteriophage (invaders of E.coli bacteria).
Enzymes are proteins that act as biological catalysts, which speed up chemical reactions, to help support life. These enzymes help to perform important tasks such as breaking foods down into energy that the body can use.
