Base pair - Wikipedia
A base pair (bp) is a fundamental unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds. They form the building blocks of the DNA double helix and contribute to the folded structure of both DNA and RNA.
Base Pair - National Human Genome Research Institute
4 天之前 · A base pair consists of two complementary DNA nucleotide bases that pair together to form a “rung of the DNA ladder.” DNA is made of two linked strands that wind around each other to resemble a twisted ladder — a shape known as a double helix.
5.4: Base Pairing in DNA and RNA - Biology LibreTexts
2022年5月15日 · The rules of base pairing explain the phenomenon that whatever the amount of adenine (A) in the DNA of an organism, the amount of thymine (T) is the same (called Chargaff's rule). Similarly, whatever the amount of guanine (G), the amount of cytosine (C) is the same.

2019年3月25日 · Base pairs refer to the sets of hydrogen-linked nucleobases that make up nucleic acids DNA and RNA. They were first described by Dr. Francis Crick and Dr. James Watson who are best known for discovering the helical, “twist around,” structure of DNA (1953).

Base pair, in molecular biology, two complementary nitrogenous molecules that are connected by hydrogen bonds. Base pairs are found in double-stranded DNA and RNA, where the bonds between them connect the two strands, making the double-stranded structures possible. Base pairs themselves are formed.

Base-pairing takes place between a purine and pyrimidine: namely, A pairs with T, and G pairs with C. In other words, adenine and thymine are complementary base pairs, and cytosine and guanine are also complementary base pairs.

9.2: Base Pairing in DNA - The Watson-Crick Model
2022年7月25日 · In 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).
Base Pairing - Biology Simple
2024年2月28日 · Base pairing in DNA involves two nucleobases connected by hydrogen bonds, creating the DNA double helix structure. This pairing consists of adenine (A) with thymine (T) and cytosine (C) with guanine (G). Base pairs are crucial for the stability and function of DNA.
