Biology

Transcribe a DNA template strand to its complementary mRNA sequence (A→U, T→A, G→C, C→G).

Formula

A→U, T→A, G→C, C→G (template strand read 3'→5')
  • RNA polymerase reads the template DNA strand in the 3'→5' direction.
  • The resulting mRNA runs 5'→3' with uracil (U) replacing thymine (T).
  • For the coding (non-template) strand, replace T with U directly.

DNA: ATGCGT

Inputs
  • DNA Template Strand (3' → 5'): ATGCGT

A→U, T→A, G→C, C→G, G→C, T→A → mRNA: UACGCA

Frequently asked questions

What is transcription?
The process by which DNA is copied into mRNA by RNA polymerase.
Why is U used instead of T?
RNA uses uracil (U) instead of thymine (T) as the complementary base to adenine.
