DNA Structure

State the two organic molecules found in the nucleus of all cells
Proteins and nucleic acids
State the organism that Hershey and Chase chose for their experiments and why are they known as parasites
They studied a special type of virus, called a bacteriophage, which infects bacteria. Viruses are tiny parasites which invade the cells of the host organism. Produce copies of themselves
State the technique used to follow proteins and nucleic acid in these experiments
Nucleic acids, which contain phosphorus but not sulfur, were labelled the bacteriophages
Outline the evidence which pointed to nucleic acids being the source of genetic material
Phosphorus (radioactive)
Sulfur (radioactive)
