Genetics and the Hershey-Chase Experiment

Who were the two scientists mentioned in the video that worked together on studying bacteriophages?

• Alfred Hershey and Martha Chase

• Gregor Mendel and Thomas Morgan

• James Watson and Francis Crick

• Rosalind Franklin and Maurice Wilkins

What is the primary function of a bacteriophage?

• To inject DNA into bacteria and replicate

• To convert bacteria into plant cells

• To protect bacteria from other viruses

• To consume bacteria for energy

How do bacteriophages affect human cells during a viral infection?

• They strengthen the immune system

• They transform cells into bacteria

• They have no effect on human cells

• They slowly kill cells one by one

What did Hershey and Chase use to label the DNA and protein coat of the virus in their experiment?

• Ultraviolet light

• Magnetic fields

• Radioactive markers

• Fluorescent dyes

What conclusion did Hershey and Chase reach regarding the genetic material responsible for inheritance?

• Proteins are the genetic material

• Carbohydrates carry genetic information

• DNA is the genetic material

• Lipids are responsible for inheritance
