hydrogen bonds
hydrogen bonding between the two bases present on two strands of dna hold the two strands. If there was no hydrogen bonding then doublex helix structure of dna would not be possible
hydrogen bonds
DNA is held together by hydrogen bonding (aka H-bonding).
Hydrogen bonding is the primary intermolecular force that holds together the two strands of DNA in your body. These hydrogen bonds form between complementary base pairs (adenine-thymine, guanine-cytosine) and contribute to the stability of the DNA double helix structure.
Hydrogen bonds hold together the two strands of DNA. These bonds form between specific base pairs: adenine (A) with thymine (T), and guanine (G) with cytosine (C), creating the double helix structure of DNA.
Hydrogen bonds do this.
The two polynucleotide strands of a DNA molecule are held together by hydrogen bonds between complementary bases. Adenine pairs with thymine and guanine pairs with cytosine. This base-pairing contributes to the structural stability of the DNA molecule.
DNA strands are held together by hydrogen bonds.
Nitrogenous bases form hydrogen bonds with one another. These hydrogen bonds are responsible for holding the two strands of DNA together in the double helix structure.
Ionic bonding holds the particles together in sodium chloride. In this type of bonding, electrons are transferred from one atom to another, resulting in the formation of charged particles called ions. Sodium donates an electron to chlorine, forming positively charged sodium ions and negatively charged chloride ions, which are attracted to each other to create the sodium chloride compound.
When two strands of DNA that have exactly complementary base pairing (Adenine bonds with only Thymine, and Cytosine with Guanine) the base forms a hydrogen bond to the base on the opposite strand, only if the base pairing is complementary. So, in short the double helix form is held together by hydrogen bonds between the bases present on the strand. This means as the two strands are split apart, a new complimentary strand is formed against each, resulting in two identical double helices where there was just one before. It is by this means that the instructions for the code of life are copied and passed on.
The ions are held in the lattice by the electrostatic force of attraction between these positive ions and the delocalised electrons. This attraction extends throughout the lattice and is called metallic bonding.
