RNase
Definition
Noun: A type of enzyme (specifically, a transferase) that catalyzes the hydrolysis of ribonucleic acid (RNA). It breaks down RNA molecules by cleaving the phosphodiester bonds between nucleotide subunits.
Usage
Rnase is a scientific term used primarily in biochemistry and molecular biology. It refers to the enzyme responsible for RNA degradation. - It is often used in laboratory protocols to remove unwanted RNA from samples. - The term is typically used in its full form "ribonuclease" in formal writing, with "RNase" being a common abbreviation.
Examples
- Noun:
- The experiment requires the addition of rnase to ensure the DNA sample is free of RNA contamination.
- RNase H is a specific type of rnase that degrades the RNA strand in an RNA-DNA hybrid.
Advanced Usage
- "RNase-free": A critical condition in molecular biology work, describing reagents, water, or labware that have been treated to remove or inactivate any ribonuclease enzymes to prevent RNA degradation.
- Always use RNase-free tubes for storing purified RNA.
- "Ribonuclease (RNase) activity": Refers to the catalytic function of the enzyme.
- The RNase activity in the cell lysate must be inhibited to isolate intact mRNA.
Variants and Related Words
- Ribonuclease (n): The full, formal name for RNase.
- RNase A, RNase H, RNase P (n): Names for specific, well-characterized types of ribonucleases with distinct functions.
- Deoxyribonuclease (DNase) (n): A related enzyme that degrades DNA instead of RNA.
- Nuclease (n): The broader category of enzymes that cleave nucleic acids, which includes both RNases and DNases.
Synonyms
- Ribonuclease: The formal synonym.
- RNA-degrading enzyme: A descriptive synonym.
Related Phrases
- RNase inhibition: The process or use of agents to stop RNase activity.
- The buffer contains an RNase inhibitor to protect the RNA during reverse transcription.
- RNase contamination: The unwanted presence of RNase in a sample or reagent, which is a major concern in RNA research.
- The failed experiment was likely due to RNase contamination.
Noun
-
a transferase that catalyzes the hydrolysis of ribonucleic acid
