Calculateur d'ARN

Transcrivez l'ADN en ARN et obtenez la composition en bases.

Introduction

RNA Calculator — Transcribe DNA to RNA and get base composition. Enter DNA sequence (coding strand) to get an instant, accurate result.

Formule

Transcribes a DNA coding-strand sequence to RNA by substituting every thymine (T) with uracil (U), leaving A, C, and G unchanged, then reports length and base composition including GC content.

Étape par étape

  1. Enter the DNA sequence (coding strand).
  2. Click Calculate to see your result instantly.

Exemple concret

Example: With DNA sequence (coding strand) = ATGCATGCTAGC, the RNA Calculator gives Rna Sequence: AUGCAUGCUAGC, Length: 12, Counts: 3, 3, 3, 3.

Questions Fréquentes

Why is uracil used instead of thymine in RNA?
RNA uses uracil in place of DNA's thymine — this tool assumes you are entering the DNA coding (sense) strand and simply swaps every T for a U to get the matching RNA sequence.
Does this transcribe the template strand or the coding strand?
It performs a direct T→U substitution on the sequence you enter, which mirrors coding-strand-to-mRNA transcription (the template strand would additionally need to be reverse-complemented first).
What inputs does the RNA Calculator need?
You'll need to provide: DNA sequence (coding strand). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the RNA Calculator?
The RNA Calculator applies the formula exactly as calculated — Transcribes a DNA coding-strand sequence to RNA by substituting every thymine (T) with uracil (U), leaving A, C, and G unchanged, then reports length and base composition including GC content. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the RNA Calculator free to use?
Yes, the RNA Calculator is completely free, requires no signup, and runs instantly in your browser.

À propos de Calculateur d'ARN

The RNA Calculator uses a real, verifiable formula — Transcribes a DNA coding-strand sequence to RNA by substituting every thymine (T) with uracil (U), leaving A, C, and G unchanged, then reports length and base composition including GC content. — so results are accurate every time, not an approximation.
