Vedclass · Answer

Beijerinck}$ $(1898)$ demonstrated that the extract of the infected plants of tobacco could cause infection in healthy plants and called the fluid as "contagium vivum fluidum" (infectious living fluid).$A$ virus is a nucleoprotein, meaning it contains genetic material (either $	ext{RNA}$ or $	ext{DNA}$) and a protein coat.No virus contains both $	ext{RNA}$ and $	ext{DNA}$ as its genetic material.Therefore, the statement that viruses contain both $	ext{RNA}$ and $	ext{DNA}$ is incorrect.

$P$. Animal virus	$I$. $ssRNA$
