Protein synthesis begins when this type of RNA is generated as the RNA polymerase binds with DNA in a process called transcription. This type of RNA also contains the genetic information in DNA. What is the RNA tye?
O rRNA
ORNA
OBRNA
OmRNA

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.
