Step 1

This means that they run in opposite directions. In this case, we are going to transcribe the DNA sequence into an mRNA sequence from the 5' end to the 3' end. Show more…

Key Concepts

Transcription

Transcription is the biological process in which RNA polymerase synthesizes an RNA molecule using a DNA template. This process involves decoding the genetic information in the DNA to produce a messenger RNA (mRNA) strand that carries the genetic message for protein synthesis.

Complementary Base Pairing

Complementary base pairing is the mechanism by which nucleotide bases form pairs across the two strands of DNA and similarly during transcription. In this process, adenine pairs with thymine in DNA (or with uracil in RNA) and cytosine pairs with guanine, ensuring that the mRNA sequence is a complementary copy of the DNA template strand.

DNA Template Strand (Antisense Strand)

The antisense strand, also known as the DNA template strand, is the strand of DNA used by RNA polymerase during transcription. It is read in the 3' to 5' direction so that a complementary mRNA strand can be synthesized in the 5' to 3' direction.
