DNA to mRNA Converter

Visualize the transcription process. Enter a 5' to 3' DNA coding sequence to see the resulting mRNA strand and its template DNA complement.

DNA Sequence (5' to 3')*

Transcription Rules (DNA → mRNA): • Adenine (A) → Uracil (U) • Thymine (T) → Adenine (A) • Cytosine (C) → Guanine (G) • Guanine (G) → Cytosine (C) Note: For the coding strand (5' to 3'), mRNA is identical except all Thymines (T) become Uracils (U).

Scenario: You have a DNA coding sequence 5'-ATG-GGC-TTA-3' and need to find the resulting mRNA transcript. Calculation: 1. Identify bases: A, T, G, G, G, C, T, T, A. 2. Apply T → U rule for coding strand transcription. 3. Result: 5'-AUG-GGC-UUA-3'. Result: The mRNA sequence is AUGCUUA.

How is DNA transcribed into mRNA?

Transcription is the process where a DNA sequence is copied into a complementary RNA sequence. The main difference is that RNA uses Uracil (U) instead of Thymine (T).

What is the complementary base pairing rule?

In RNA transcription: DNA A pairs with RNA U, DNA T pairs with RNA A, DNA C pairs with RNA G, and DNA G pairs with RNA C.

What is the difference between the coding and template strand?

The template strand is the one actually read by RNA polymerase. The mRNA sequence is complementary to the template strand and identical to the coding strand (except U replaces T).

Can I use this for translation too?

This specific tool focuses on transcription (DNA to mRNA). Translation (mRNA to Protein) involves reading codons, which is a separate step in the central dogma.
