Solution

The correct option is B TMV
Fraenkel Conrat was a biochemist and famous for his viral research. He did research on tobacco mosaic virus (TMV) and the holmes ribgrass virus (HRV). He discovered that the genetic control of viral reproduction was RNA and that it is carried in the nucleic core of each virus of TMV. In 1955 he and Robley Williams showed that a functional virus of TMV could be created out of purified RNA and a protein coat. In 1960 he announced the complete sequencing of the 158 amino acids in the TMV.
So, the correct answer is 'TMV'.
