IB Biology Topic D1.2.2 Role of Hydrogen Bonding and Complementary Base Pairing in Transcription Revision Notes (SL/HL) | RevisionDojo

Written by official IB examiners

Complementary base pairing and hydrogen bonding make transcription accurate

Complementary base pairing between the DNA template and incoming RNA nucleotides decides which base is added at each position.
Hydrogen bonds between the paired bases hold each new nucleotide in place long enough for RNA polymerase to add it correctly.

Each DNA base pairs with one specific RNA base

During transcription the DNA template strand is read base by base, and each base pairs with its complementary RNA nucleotide.
1. A in the template pairs with a U in the RNA, because RNA uses uracil in place of thymine.
2. T in the template pairs with an A in the RNA.
