A weak hydrogen bond,
adenine and thymine have a double hydrogen bond
cytosine and guanine have a triple hydrogen bond
Describe how each of the DNA nitrogen bases pair together
The nitrogen bases, adenine, uracil, guanine, thymine and cytosine are joined to each other via phosphodiester bonds. Hydrogen bonds hold the nitrogen bases in complementary DNA and RNA strands. Polypeptide bonds are formed between an amide and ketone, and these join amino acids in proteins. However, they do not hold nitrogen bases together.
The nitrogen bases are held together by hydrogen bonds.
Nitrogen bases form together through hydrogen bonding between complementary bases (adenine with thymine, and cytosine with guanine). This base pairing allows for the formation of a stable double helix structure in DNA.
The nitrogen bases are held together in the center of the DNA molecule by hydrogen bonds. These bonds form between specific base pairs: adenine (A) with thymine (T), and guanine (G) with cytosine (C). The hydrogen bonds provide stability to the DNA double helix structure.

transcription
Hydrogen bonds hold nitrogen-containing bases together in DNA. These bonds form between adenine and thymine (A-T) and between cytosine and guanine (C-G) in a DNA double helix.
A nitrogen bases
Nitrogen bases in DNA bond together through hydrogen bonds. Adenine pairs with thymine through two hydrogen bonds, while guanine pairs with cytosine through three hydrogen bonds. These base pairs form the rungs of the DNA ladder structure.
