DNA to mRNA Converter

Transcription converts a DNA sequence into mRNA — the messenger molecule that carries genetic instructions from the nucleus to the ribosome for protein synthesis. Enter your DNA Sequence (A, T, G, C only), select whether it's a Template Strand or Coding Strand, and choose a Genetic Code to get the transcribed mRNA Sequence, translated Protein Sequence, sequence length in nucleotides, and amino acid count. Also try the find GC Content with GC Content Calculator.

DNA Strand Type *

Template strand is complementary to mRNA; coding strand has same sequence as mRNA (except T instead of U)

Enter your DNA sequence using only A, T, G, C nucleotides

Select the genetic code table to use for translation

Frequently Asked Questions

What is the difference between DNA and mRNA?

DNA uses thymine (T) while mRNA uses uracil (U). DNA is double-stranded and contains deoxyribose sugar, while mRNA is single-stranded and contains ribose sugar. mRNA is synthesized from DNA during transcription.

How do I transcribe DNA to mRNA?

To transcribe DNA to mRNA, replace each DNA base with its complement: A→U, T→A, G→C, C→G. If using the template strand, create the complement. If using the coding strand, simply replace T with U.

What is the difference between template and coding strands?

The template strand is complementary to the mRNA sequence and serves as the template during transcription. The coding strand has the same sequence as mRNA (except T instead of U) and is also called the sense strand.

How is mRNA translated to protein?

mRNA is translated to protein using the genetic code, where every three nucleotides (codon) specify one amino acid. Translation begins at a start codon (AUG) and ends at stop codons (UAA, UAG, UGA).

What are the 3 types of RNA?

The three main types of RNA are: mRNA (messenger RNA) that carries genetic information, tRNA (transfer RNA) that brings amino acids during translation, and rRNA (ribosomal RNA) that forms the structure of ribosomes.

Why might I get different results with different genetic codes?

Different genetic codes exist because some organisms (like mitochondria) use slightly different codon assignments than the standard genetic code. This affects which amino acids are produced during translation.
