Answer:
Hershey Chase and Griffith experiment supported the same conclusion which was: DNA is the molecular substance of genetic inheritance.
Explanation:
Both experiments have was based on different phenomenon and techniques to prove same conclusion.
Hershey and chase conducted an experiment via bacteriophage which consists to DNA and protein coat that infects bacterial cells. He proved the DNA as genetic material by the help of transduction mechanism (Incorporation of Bacteriophage DNA in to bacterial cells). He used two group of Bacteriophage 1st group of Phage contain radioactively labelled proteins by Sulphur 32 isotope. While 2nd group contain Bacteriophage having P32 labelled DNA to infect Bacterial cells. After the infection, the Reaction tubes subjected to centrifuge and presence of radioactivity was determined in pellet and supernatant. The 1st group show radioactivity in supernatant while 2nd group shows racdioactivity in pellet or bacterial cells.
Griffiths just hypothesized a substance that can be transmitted from dead organism to alive organisms with the help of transformation phenomenon (uptake of Genetic material from the surrounding or environment). He conducted his experiments on <em>Streptococcus pneumonia avirulent and virulent species. </em>By mixing dead virulent species and live avirulent species and injecting into the mice results in the death of an experimental animal. While alone dead virulent species and live avirulent species fail to cause disease in mice.
They classify on how they reproduce.
You should use the smallest unit rate any time accuracy is needed. For example, if you are administering dosages of vaccines, you should use the smallest syringe possible for the dosage. A smaller syringe will have more precise graduations than a larger one. The same holds true for glassware such as graduated cylinders. A 1000 ml graduated cylinder will probably not have a 5 ml graduation on it, and measuring out 5 ml with a cylinder that large would be guesswork at best. A 10 ml graduated cylinder, however, will have graduations for every 0.1 ml, and would be suitable for measuring small amounts of liquids.
