Comparison ยท Science
RNA vs DNA
RNA helps express and regulate genes; DNA stores genetic instructions.
RNA
- single strand
- uracil
- short-lived
- messenger roles
DNA
- double helix
- thymine
- stable storage
- replicates
Core Difference
RNA is single-stranded and often temporary; DNA is double-stranded long-term storage
Use Cases
DNA stores genomes; RNA carries messages or functional roles like tRNA and rRNA
Verdict
DNA preserves code; RNA executes and regulates expression
