Ribonuclease V1 (RNase V1) is a ribonuclease enzyme found in the venom of the Caspian cobra ("Naja oxiana"). It cleaves double-stranded RNA in a non-sequence-specific manner, usually requiring a substrate of at least six stacked nucleotides. Like many ribonucleases, the enzyme requires the presence of magnesium ions for activity. Using only the above description and what you know about the world, "RNase V1is a poison found in cobras. Cobras are found in many countries and are considered extremely deadly. " is definitely correct, incorrect, or inconclusive?
