What molecule carries the genetic code?
OBJECTIVE
How did biologists discover the molecule responsible for the genetic code?
Use pages 338-341 in the textbook to answer the questions.
INTRODUCTION
Organisms are able to do some remarkable things. Starfish can reproduce from just one of their
arms. Female sage grouse know which male will make the best father based on a complex mating
dance. Cutthroat trout find their way back to the stream in which they were born. It is as though
organisms are driven by a pre-installed genetic code. But what is this genetic code?
In the early 1900s, a series of experiments were designed to shed light on a genetic code that seems
to program organisms. Write a summary of your assigned experiment and use a correlating poster
to present the experiment to the class.
