Which of the following experimental results was NOT evidence that DNA is the genetic molecule rather than proteins? a. When a virus was radioactively labelled, and the virus was allowed to infect a bacteria cell, radioactive virus DNA was found inside the bacteria cell while radioactive virus proteins were found outside the cell. b. Dead pathogenic bacteria cells combined with living nonpathogenic bacteria cells caused the creation of living pathogenic cells and thus the death of the host animal. c. Proteins are a class of macromolecules with the diversity and specificity needed for hereditary material. d. Nucleotide bases occur regularly, such that the number of adenines = number of thymines, and the number of guanines = number of cytosines.

You are working in the lab and have measured the size of mRNA that has been transcribed from a particular gene in your cell population. The length of the gene in the cells you are working, measured from the start to the stop sequence is 9000 nucleotides. When you measure the RNA, however, the size is only 3000 nucleotides. What do you think happened? O a. Three DNA base pairs code for one RNA nucleotide. b. mRNA does not contain exons. c. There must have been a deletion mutation in the DNA in these cells. Od. The poly-A tail is present in the DNA but not on the mRNA. Oe. RNA splicing occurred, so introns are removed in the mRNA.
