The Hershey and Chase experiments showed that the inherited genetic material was DNA (deoxyribonucleic acids). In this experiment, the scientists labelled the DNA molecule with a radioactive isotope of phosphorus.
Centrifugation causes the separation of different components according to their size. So, by blending, they centrifugated the mixture of virus and the bacteria, which separated the viral protein capsule and the bacteria. Later, they found that the virus infected bacteria contains the DNA of bacteria, not the protein.
Hence, bacterial cultures infected with a virus were agitated in a kitchen blender to separate the protein coat of virus from the bacteria.
Answer:The major difference between atomic number and mass number is that the atomic number states the number of protons present in an atom whereas, the mass number indicates the total of the number of protons and the number neutrons present in an atom.i) Atomic number is the total number of protons present in the nucleus of an atom. It is also equal to the number of electrons for a neutral atom. Example, atomic number of sodium is 11. ii) Mass number is the number of protons and neutrons in the nucleus taken together. For example, mass number of sodium is 23 g/mol.
hope this helps have a great night❤️❤️❤️❤️
Explanation:
Answer:
To which group of macromolecules does this compound most likely belong? B) Protein
Explanation:
If the chemichal analysis of the compound showed carbon, hydrogen, oxygen, nitrogen and phosphorus, we would we talking about nucleic acid. Lipids would not be a possibility because they are made of hydrocarbons. When it comes to carbohydrates, they are made of carbon, hydrogen and oxygen. Protein is the right answer because they are made of carbon, hydrogen, oxygen, nitrogen, and sulfur.
