How do the structures ribosomes and ER work together? To synthesize lipids and modify toxic substances so that they are harmless

To synthesize and isolate proteins for distribution and use in the cell

To break down glucose in order to create ATP

RNA leaves the nucleus to be translated by ribosomes

The hershey and chase experiments involved the preparation of two different types of radioactively labeled phage. which of the following best explains why two preparations were required? a. the bacteriophage used in the experiments was a t2 phage. b. it was necessary that each of the two phage components, dna and protein, be identifiable upon recovery at the end of the experiment. c. each scientist had his own method for labeling phage, so each conducted the same experiment using a different isotope. d. establishing the identity of the genetic material required observation of two phage generations.
