History of DNA Discovery

• Before 1928, scientists didn't know what carried
  genetic information.

  Many believed _______ were the molecule directly
  responsible for inheritance.

• Lipids

• Proteins

• Nucleic Acid

• Carbohydrates

• Which of the following are not one of the three key experiments contributed to our current
  understanding of hereditary material?

• • Griffith's Transformation Experiment

• • Avery-MacLeod-McCarty Experiment

• Watson and Crick

• • Hershey-Chase Experiment

What was the name of the bacterium that Frederick Griffith studied?

• Streptococcus pneumonia

• Staphylococcus epidermis

• Salmonella

• E. coli

Through
experimentation and
research of __________,
Griffith discovered the
process of
transformation.

• Streptococcus pneumonia and rabbits

• Streptococcus pneumonia and mice

• Staphylococcus epidermis and rabbits

• Staphylococcus epidermis and mice

Bacterial transformation is the process of a
bacterium uptaking external, exogenous genetic
material and incorporating it into their own
genome.

• One of the biggest implications we now know of
  is the transfer of advantageous genes, such as
  antibiotic resistance, through __________.

• absorption

• augmentation

• conjugation

• transformation
