What evidence allowed Hershey and Chase to show that DNA alone carried the genetic information of a bacteriophage?

A nucleotide does NOT contain a. a 5 -carbon sugar b. an amino acid c. a nitrogen base d. a phosphate group

Hershey and Chase hoped to find out whether DNA or protein carried the genetic information of a virus. The scientists used radioactive substances to label the DNA in some viruses. They used the protein coat in other viruses. Then they let the viruses inject their genetic material into bacteria. Answer the question: What result did Hershey and Chase's experiment have in the scientific community?

Before DNA could definitively be shown to be the genetic material in cells, scientists had to show that it could a. tolerate high temperatures b. carry and make copies of information c. be modified in response to environmental conditions. d. be broken down into small subunits

The process by which one type of bacteria is changed into another type is called a. transcription b. transformation c. duplication d. replication

Which of the following researchers used radioactive markers in experiments to show that DNA was the genetic material in cells? a. Frederick Griffith b. Oswald Avery c. Alfred Hershey and Martha Chase d. James Watson and Francis Crick
