Best Answer

Because DNA is bigger and fixed in position by proteins, so it is more stable and well protected. Considering that it contains huge amount of genitic code for a human, it is more suitable for this purpose; while double stranded RNA is only suitable for carrying rather simpler genitic code, i.e. rotaviruses.
