DNA consists of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. The sequence of nucleotides determines individual hereditary characteristics.
Hydrogen bonds in double-strand DNA help to stabilize the structure by forming base pairs between complementary nucleotides (adenine-thymine, guanine-cytosine). This allows the two strands to stay together, ensuring proper replication and transmission of genetic information during cell division.
The double helix containsamino acids bonded together, (one might say it is a polymer) this is called a protein and it is what the each single strand of the helix consists of. this is because the two strands contain alternating hydrogen and oxygen which form hydrogen bonds with each other.
the purpose for hydrogen bonds is to hold the 2 strands of DNA together
Hydrogen bonds hold the DNA bases together!
Strong hydrogen bonds.
The bonds that join the DNA sides are called hydrogen bonds. These bonds form between complementary base pairs (adenine with thymine, and guanine with cytosine) on the two strands of the DNA double helix. This hydrogen bonding is essential for maintaining the structure and stability of the DNA molecule.
Thymine. Two hydrogen bonds connect adenine to thymine in the DNA molecule.

Hydrogen Bonds
Hydrogen bonds hold the DNA bases together!
Strong hydrogen bonds.
DNA bases are held together by hydrogen bonds. Adenine pairs with thymine through two hydrogen bonds, while guanine pairs with cytosine through three hydrogen bonds. These interactions contribute to the stability of the DNA double helix structure.
Hydrogen bonds
Bases in DNA are linked through hydrogen bonds. There are two hydrogen bonds between Adenine and Thymine There are three hydrogen bonds between Guanine and Cytosine
DNA is composed of covalent bonds. The backbone of DNA is made up of sugar-phosphate molecules linked by covalent bonds, while the bases are held together by hydrogen bonds. The overall structure of DNA is stabilized by a combination of covalent and hydrogen bonds.
Hydrogen bonds are the bonds that hold the two strands of DNA together. Each base pair in DNA is held together by hydrogen bonds between complementary nitrogenous base pairs - adenine pairs with thymine (or uracil in RNA) with two hydrogen bonds, and guanine pairs with cytosine with three hydrogen bonds.
The bonds that hold together DNA are hydrogen bonds between complementary base pairs: adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). These base pairs form the "rungs" of the DNA double helix, which is stabilized by sugar-phosphate backbones of the DNA strands.
Cytosine can hydrogen bond to guanine. In DNA, cytosine forms three hydrogen bonds with guanine, while in RNA, it forms two hydrogen bonds with guanine. These hydrogen bonds help stabilize the DNA double helix structure.
Hydrogen bonds hold the bases of the two strands of DNA together. These bonds form between complementary nucleotide base pairs (adenine-thymine and guanine-cytosine) in the double helix structure of DNA.
