In molecular Biology and genetics, the linking between two nitrogenous bases on opposite complementary DNA or certain types of RNA strands that are connected via hydrogen bonds are called a base pair (often abbreviated bp). In the canonical Watson-Crick DNA base pairing, adenine (A) forms a base pair with thymine (T) and guanine (G) forms a base pair with cytosine (C). In RNA, thymine is replaced by uracil (U). Alternate hydrogen bonding patterns, such as the wobble base pair and Hoogsteen base pair, also occur-in particular, in RNA-giving rise to complex and functional tertiary structures. Pairing is the mechanism by which codons on messenger RNA molecules are recognized by anticodons on transfer RNA during protein translation. Some DNA- or RNA-binding enzymes can recognize specific base pairing patterns that identify particular regulatory regions of genes.
The size of an individual gene or an organism's entire genome is often measured in base pairs because DNA is usually double-stranded. Hence, the number of total base pairs is equal to the number of nucleotides in one of the strands (with the exception of non-coding single-stranded regions of telomeres). The haploid human genome (23 chromosomes) is estimated to be about 3 billion base pairs long and to contain 20,000-25,000 distinct genes. A kilobase (kb) is a unit of measurement in molecular biology equal to 1000 base pairs of DNA or RNA.
adenine is paired with thymine, and cytosine is paired with guanine.
Adenine - Thymine
Cytosine - Guanine
Adenine pairs with Thymine
Cytosine pairs with Guanine
Adenine and Thymine, Cytosine and Guanine
C pairs with G. A pairs with T.
hydrogen bonds
Adenine pairs with Thymine ( A-T) Guanine pairs with cytosine ( G-C)
In DNA: Adenine base pairs with Thyamine A=T In RNA: Adenine base pairs with Uracil A=U
The complementary DNA strand is CGTTTGATGG. A pairs with T, and G pairs with C.
If one strand of DNA has a nucleotide base sequence of tcaggtccat, its complementary strand is agtccaggta. Adenine pairs with thymine, while guanine pairs with cytosine.
hydrogen bonds
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.
So essentially the difference is that in DNA-DNA base pairs thymine bonds with adenine while in DNA-RNA base pairs thymine bonds to uracil.
Adenine pairs with Thymine ( A-T) Guanine pairs with cytosine ( G-C)

In DNA: Adenine base pairs with Thyamine A=T In RNA: Adenine base pairs with Uracil A=U
There are four nucleotides that combine together in DNA to form its two base pairs. Adenine (A) pairs with thymine (T). Cytosine (C) pairs with guanine (G). When RNA transcribes these pairs from the original DNA molecules, uracil (U) pairs with adenine, replacing thymine.
The complementary DNA strand is CGTTTGATGG. A pairs with T, and G pairs with C.
If one strand of DNA has a nucleotide base sequence of tcaggtccat, its complementary strand is agtccaggta. Adenine pairs with thymine, while guanine pairs with cytosine.
In DNA, C pairs with G, and A pairs with T.This means that GCATA is complementary to CGTAT.
They are: - Adenine and thymine - Cytosine and guanine
