Chapter 14 DNA: The Genetic Material

 

Viruses that attack bacteria are called?

• pneumococcus

• transformation

• bacteriophages

 

Which scientist Identified that DNA (not proteins) was responsible for the transformation

• Griffith

• Hersey-Chase

• Avery

• Watson and Crick

 

The results of the Hershey-Chase Experiment

• the hereditary info is found in the proteins

• the hereditary info is found in the DNA

• the hereditary info is found in the amino acids

Mice given virulent S strain

• Lived

• died

Mice given mutant R strain

• Lived

• died

Mice given the heat killed S strain

• lived

• died

Mice given the mixture of heat killed S strain with live R strain

• lived

• died

Which experiment used radioactive isotopes as tracers into viruses

• Griffith

• Avery

• Hershey-Chase

 

Which experimented with pathogenic bacteria-Pneumococcus/pneumonia?

• Griffith

• Hershey-Chase

• Avery

Griffith found that the transfer of genetic material from one cell to another; can alter the genetic makeup of the recipient cell.

• transformation

• bacteriophages

• DNA replication

• translocation
