Ch. 12 DNA

Hershey and Chase's experiment led to what hypothesis?

• DNA was genetic material found in all living cells
• DNA is only found bacterial cells
• DNA is only found in sex cells
• Protein transmits genetic information from one generation to the next

Why is it important that DNA can be accurately copied?

• it is not important
• so it keeps it molecular structure
• so that each daughter cell receives a complete and correct copy of the genetic material
• so that we are all identical in genetic makeup
