To solve this problem, we need to analyze the given statements:$\newline$Statement I: RNA mutates at a faster rate.$\newline$Statement II: Viruses having RNA genome and shorter life span mutate and evolve faster.$\newline$Let's break down each statement:$\newline \bullet$Statement I:$\newline$ - RNA viruses are known to have higher mutation rates compared to DNA viruses.$\newline$ - This is because RNA-dependent RNA polymerases, which replicate RNA genomes, lack proofreading ability.$\newline$ - As a result, errors during replication are more frequent, leading to faster mutation rates.$\newline$ - Therefore, Statement I is true.$\newline \bullet$Statement II:$\newline$ - Viruses with RNA genomes often have shorter life cycles, allowing them to reproduce quickly.$\newline$ - The combination of high mutation rates and rapid reproduction leads to faster evolution.$\newline$ - This enables RNA viruses to adapt quickly to changing environments or host defenses.$\newline$ - Therefore, Statement II is true.$\newline$Since both statements are true, the correct answer is Option 1: Both Statement I and Statement II are true.
