The experiments by hershey and chase confirm that dna was the hereditary material on the basis of the finding that:
radioactive phage were found in the pellet
radioactive cells were found in the supernatant
radioactive sulfur was found inside the cell
radioactive phosphorus was found in the cell

Imagine that certain laws of physics could be ignored and you were able to travel vast distances in moments. now imagine that you traveled to an earth-like planet located light-years away that is known to support life. think about what you’ve learned in this unit and make an argument for what you think would be the dominant type of life form on this planet. consider whether a notochord is required for an organism to manipulate its environment and become a dominant creature.
