Question

What conclusions resulted from the hershey-chase experiments? group of answer choices

O hershey and chase concluded that phage were injecting dna into bacteria and that it was the injected dna that coded for the manufacturing of new viruses.
O hershey and chase concluded the two strands of dna ran opposite of each other in order to bind together.
O hershey and chase concluded each nucleotide was complementary to another. adenine was complementary to thymine and guanine was complementary to cytosine.
O hershey and chase concluded the structure of dna was a double helix and was held together by hydrogen bonds.

Answer 1

The Hershey-Chase experiments concluded that DNA, not protein, was the genetic material responsible for creating new viruses, as demonstrated by radioactive labeling and infection patterns in bacteria. Therefore correct option is A

Step-by-step explanation:

The conclusions that resulted from the Hershey-Chase experiments were that Hershey and Chase concluded phage were injecting DNA into bacteria and that it was the injected DNA that coded for the manufacturing of new viruses. In their experiment, Hershey and Chase used radioactive labeling of DNA and protein components of bacteriophages. They demonstrated that after infection of the bacteria, only the DNA (labeled with radioactive phosphorus, 32P) entered the bacterial cells, not the protein (labeled with radioactive sulfur, 35S). This meant that the genetic material responsible for the creation of new viruses was indeed the DNA, not the protein.

Other conclusions from their work lead to the discovery of nucleotide pairing, but it was the proof of DNA as genetic material that is the direct answer to this question.
