complementary base pairing


Also found in: Encyclopedia.

complementary base pairing

the arrangement of NUCLEOTIDE BASES so that purines bond with pyrimidines, as occurs in the two polynucleotide chains of DNA (adenine with thymine, guanine with cytosine) and between DNA and MESSENGER RNA nucleotides during TRANSCRIPTION. See Fig. 136.

miRNAs have become the focus of many researchers because of their significant role in the degradation of mRNA, post-translational inhibition through complementary base pairing (4), and ability to control many biological processes such as homeostasis (3).
The chemical base structure determines the principle of complementary base pairing, which is known as the Watson-Crickbase pairing principle, namely, A bonds with T using two hydrogen atoms and G bonds with C using three hydrogen atoms [14,15].
Fusing two single stranded DNA molecules by complementary base pairing is also called annealing.
The students already knew about complementary base pairing from a previous chapter, so I had them collaborate in pairs to work on the base pairing for DNA, mRNA, and tRNA, noting the replacement of thymine (T) by uracil (U) in RNA.
