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.

Viral Replication

The virus is acellular and considered non-living outside the host cell. The replication of the virus occurs only inside the living cells. Only a few genes are present in the smallest virus, whereas many genes are present in the largest virus. These genes encode specific viral proteins.
