Meaning and Definition
An enzyme that catalyzes the breakdown of RNA into smaller components.
Any of a group of enzymes, often used in research and therapeutics, that degrade ribonucleic acid (RNA) by hydrolyzing phosphodiester bonds, playing crucial roles in cellular RNA processing, turnover, and defense mechanisms.

Common Mistakes When Using “ribonuclease”
- Misspelling as 'ribonuclase', 'ribonucleace', or 'ribonuklease'.
- Incorrect pronunciation placing primary stress on the first syllable (e.g., /'raɪbəʊ.../). Correct stress is on 'nu' or 'nucle'.
- Using it in non-scientific contexts where 'enzyme' or a simpler term would suffice.
FAQ
Frequently Asked Questions
No. Ribonuclease (RNase) specifically degrades RNA, while DNase (deoxyribonuclease) degrades DNA. They are different enzymes with different substrates.
It is used to remove unwanted RNA from samples, for example, when purifying DNA, or to study RNA structure and function by controlled digestion.
Yes. Unwanted RNase contamination is a major issue when working with RNA, as it can rapidly degrade RNA samples. Labs use RNase-free techniques and inhibitors to prevent this.
Yes. There are many types (e.g., RNase A, RNase H, RNase III) that differ in their source, structure, and specificity—some cut RNA at specific sequences, while others are non-specific.
An enzyme that catalyzes the breakdown of RNA into smaller components.
Ribonuclease is usually technical / scientific in register.
Ribonuclease: in British English it is pronounced /ˌraɪbəʊˈnjuːklɪeɪz/, and in American English it is pronounced /ˌraɪboʊˈnuːklɪeɪs/. Tap the audio buttons above to hear it.
