The chemical bond that holds the double helix together in DNA are the hydrogen bonds. Hydrogen bonds are the weakest making them perfect for DNA replication.
Double Replacement
A double arrow shows that the reaction is reversible, it represents an equilibrium in which the products on the right can react together and produce the left hand side. A chemical equation without a double arrow isn't reversible and can only go in one direction.
This is called a covalent bond.
A chemical reaction in which two elements or radicals change places with two other elements is called double replacement. It is also known as double displacement. Its general pattern can be written as AB + CD --> AD + CB
The chemical reaction is the H2O bond with O2.
Hydrogen bonds are responsible for holding the two strands of DNA together.
Hydrogen bonds do this.
The double-stranded DNA molecule is held together by four chemical components called bases. Horse isle Real Time Quiz Answer: Bases
Hydrogen bonds
A double bond.
The region of a chromosome holding the two double strands of replicated DNA together is called a centromere. The complex of DNA and protein that makes up eukaryotic chromosome is properly called chromatin.
A double arrow shows that the reaction is reversible, it represents an equilibrium in which the products on the right can react together and produce the left hand side. A chemical equation without a double arrow isn't reversible and can only go in one direction
If by "weak chemical bonds" you are referring to intermolecular attractions, which are weaker than chemical bonds, but still sufficiently strong enough to hold certain molecules together, then they are very important. DNA, for instance, forms itself into a double-helix shape, the structure of which is held together by the attraction between molecules. This attraction is not a bond (ionic or covalent); but it is an electrostatic binding, which forms a framework for this vital molecule.
The general term is "chemical reaction". There are sub-categories like "oxidation-reduction", "double (and single) replacement", and others.
There are more than one type of chemical reaction. -liquid -solid It's when two objects or liquids mix together causing a chemical reaction. By: Sarah P. Stewart
DNA is a complex chemical with a double-helix structure.
DNA organization of Eukaryotes has the nucleic acids A pair with T and C pair with T in a double helix formation. Proteins help keep this all together along with hydrogen bonds holding the subunits of DNA together while covalent (strong) bonds hold the two strands together to make the double helix.
