FAQ
Frequently Asked Questions
It is almost universally pronounced letter-by-letter: "R-N-Ase" (/ˌɑːr ɛn ˈeɪz/).
RNases are ubiquitous in the environment, particularly on skin surfaces and in bodily secretions, which is why RNase contamination is a major concern in RNA work.
It describes reagents, equipment, or conditions that have been treated to remove or inactivate RNase enzymes, thereby protecting RNA samples from degradation.
No, standard RNases are specific for RNA. Enzymes that degrade DNA are called DNases (deoxyribonucleases).
An enzyme that catalyzes the hydrolysis of RNA.
Rnase is usually technical/scientific in register.
Learning
Memory Aids
Mnemonic
RNA-Se: Think 'RNA' + the enzyme suffix '-ase'. It's the 'ase' (enzyme) that acts on RNA.
Conceptual Metaphor
MOLECULAR SCISSORS: RNase is conceptually a pair of scissors that specifically cuts RNA strands.
