WebIn double stranded DNA, the guanine (G) base on one strand can form three H-bonds with a cytosine (C) base on another strand (this is called a GC base pair). The thymine (T) base on one strand can form two H-bonds with an adenine (A) base on the other strand (this is called an AT base pair). WebBase pairs are found in double-stranded DNA and RNA, where the bonds between them connect the two strands, making the double-stranded structures possible.
