Base pair complementarity ensures faithful DNA replication. Remember that a base can only pair with a definite pair and not with just about any base therefore this ensures high fidelity of replication. If guanine can only pair with cytosine the same way that adenine can .only pair with thymine then the copying of the DNA will be accurate.
It allows enzymes such as RNA polymerase to attach the correct base to the new strand, and therefor conserve your genetic code (keep it the same).
if A-T is paired with G-C then it must be complementary.
Base pairing in DNA is important because it insures that the DNA molecule is replicated or transcribed exactly the same way every time.
complimentary For example, if the DNA codon is GCA, the complimentary mRNA codon will be CGU, according to the base pairing rule.
mRNA makes a complimentary copy of the DNA molecule according to the base-pairing rule.
DNA Lesions are sites of damage in the base-pairing or structure of DNA.
Diploid cells
In terms of DNA base pairing, adenine and thymine are complimentary bases. Therefore, for every base of adenine, there will be a base of thymine to compliment it. Therefore, cells contain the same amount of the bases adenine (A) and thymine (T).
Because if the pairing of the bases is incorrect then a mutation will form that can be silent or deadly .
Adenine binds toThymineCytosinebinds toGuanineThe shapes of the bases are specific and can only fit their complimentary base. Hydrogen bonds hold them together. In RNA Thymine is replaced by Uracil.

complimentary For example, if the DNA codon is GCA, the complimentary mRNA codon will be CGU, according to the base pairing rule.
Base pairing refers to the pairing of complimentary nitrogen bases, either during DNA replication, or transcription and translation. In DNA, the bases adenine and thymine pair together, and guanine and cytosine pair together. In RNA, the base uracil takes the place of the base thymine. The bases that pair together are said to be complimentary to each other.
The base-pairing during transcription is the same as when DNA replicates, except that RNA has uracil instead of thymine.
A complimentary codon is one that pairs with another codon according to the base pairing rule. For example, the DNA codon ATG is complimentary to the mRNA codon UAC.
mRNA makes a complimentary copy of the DNA molecule according to the base-pairing rule.
DNA Lesions are sites of damage in the base-pairing or structure of DNA.
Base Pairing Rules
James Watson and Francis Crick are credited with the base pairing rules and DNA structure in general. Erwin Chargaff is credited with the rules of base pairs in that the number of pyrimidines is equal to the number of purines.
