From DNA to Protein

Define Ribosomal RNA:

• Contains the information transcribed from DNA

• Main component of ribosomes, which build polypeptide chains

• Delivers amino acids to ribosomes during translation

In which part of the cell does this process shown in Figure 8.3 take place?

• in the nucleus

• in food vacuoles

• at the ribosomes

• on the chromosome

How did Hershey and Chase's use of radiolabeled bacteriophages to study the genetic material validate Avery's research?

• it demonstrated conclusively that the genetic material is not protein

• it showed that bacteriophages are not digested by bacterial enzymes

• it proved that bacteria will take up phosphorus, but not sulfur

• it confirmed that bacteriophages cannot inject radiolabeled DNA
