RNA Molecular Weight Calculator

Enter RNA Sequence

How to Use RNA Molecular Weight Calculator:

1. Enter the RNA sequence using A, U, G, C (case-insensitive).
2. Select the 5′ phosphate type (monophosphate, triphosphate, or none).
3. Click “Calculate Molecular Weight” to get the molecular weight in g/mol.
4. Use “Copy Result” to copy the results (requires HTTPS).

RNA Molecular Weight Examples:

1. Short Sequence:
   Sequence: AUGC, Phosphate: Monophosphate
   Expected: 1253.80 g/mol
2. Triphosphate:
   Sequence: AUGC, Phosphate: Triphosphate
   Expected: 1412.80 g/mol
3. No Phosphate:
   Sequence: AUGC, Phosphate: None
   Expected: 1174.80 g/mol
