The base pairings are ALWAYS the same; where Adenine pairs with Thymine and Guanine pairs with Cytosine. As long as there is one strand of DNA with these bases as templates, the other strand can always be determined. DNA replication always uses an old strand and uses it as the template for creating the new strand.
Ex: ATTGCCGTAAT is the old strand of DNA.
The complimentary strand is TAACGGCATTA.
The base pairings will always be the same because of the DNA polymerase which checks the pairings and fixes any mistakes. It is very rare for mistakes to occur.
During transcription of RNA or DNA base pairing is essential to keep cell genetics consistent. In DNA the base pairing formula is what determines everything that is us all the way down to what proteins needed for cellular reproduction to immune functions. Uracil will replace Thiamine during RNA transcription. Mutation will occur if the base pair is changed.
Adenine always pairs with thymine in DNA and uracil in RNA and guanine always pairs with cytosine in both DNA and RNA. The fact that the bases always pair in a specific pattern ensures the accuracy of the mRNA transcribed from the DNA template.
The process of base pairing helps to ensure that DNA is replicated (sorry not sure about transcribed) accurately through the semi-conservative replication methods.
Thymine
This is false transcription does not follows the same base-pairing rules as DNA replication except for cytosine which has a different partner. Transcription begins with an enzyme called RNA polymerase.
base pairing rules
Base pairing rules and complementary base rules are related because of DNA. If one can find the base pairing on a strand of DNA, usually the complementary base is easily found.
an enzyme called DNA helicases unwinds the double helix before DNA replication begins. enzymes known as DNA polymerases move along each of tge DNA strands while adding nucleotides to the exposed nitrogen bases according to the base pairing rules.
DNA replication simply means that DNA will split the double helix in two and refill its self. which then will make two of the same DNA strands.

DNA replication
DNA polymerases add nucleotides to the exposed base pairs according to base-pairing rules.
Base Pairing Rules
The difference between transcription and DNA replication is that transcription uses uracil.
base pairing rules
During DNA replication, the DNA molecule separates into two strands, then produces two new complementary strands following the rules of base pairing. Each strand of the double helix of DNA serves as a template, or model, for the new strand.
DNA cannot replicate de novo (i.e. there must be a free 3' OH group to attach nucleotides to) Replication must go from 5' to 3' The two strands of DNA are antiparallel Complementary base pairing
