RNase A is a type of enzyme that specifically breaks down ribonucleic acid (RNA) molecules. It is derived from the pancreas of cows and is commonly used in laboratory research to remove RNA from samples. This enzyme works by cleaving the RNA into smaller pieces, which helps scientists study DNA and proteins without interference from RNA. In addition to its research applications, RNase A has potential therapeutic uses. It can be utilized in the development of antiviral treatments, as it may help degrade viral RNA. Its ability to target RNA makes it a valuable tool in molecular biology and biochemistry.
