Detailed Solution

Both statement I and statement II are true.
SI: RNA mutates at a faster rate compared to DNA. This is due to the inherent properties of RNA replication.
SII: Viruses having RNA genome and having shorter lifespan mutate and evolve faster. This is because RNA viruses, such as influenza virus and HIV, have high mutation rates during replication. Their shorter generation times and large population sizes allow for rapid genetic changes and adaptation to new environments, leading to faster evolution.
