- The strong bonds between the DNA chains are the hydrogen bonds (H-bonds). The H-bonds exist between the base pairs. 2 H-bonds exist between Adenine and Thymine and only 3 H-bo … nds exist between Guanine and Cytosine. This means that A-T bonds are stronger than C-G, this difference arises purely because of slight chemical differences in the bases. Within the chains the strong bonds are covalent. These covalent bonds are found between the sugar group of one nucleotide and the phosphate group of another.

- Covalent bonds occur when electrons are shared between two atoms. A single covalent bond is when only one pair of electrons is shared between atoms. A sigma bond is the strongest type of covalent bond, in which the atomic orbitals directly overlap between the nuclei of two atoms.

How are sugars and phosphates held together in a DNA backbone? Phosphodiester bonds are central to all life on Earth, as they make up the backbone of the strands of DNA. In DNA and RNA, the phosphodiester bond is the linkage between the 3' carbon atom of one sugar molecule and the 5' carbon of another, deoxyribose in DNA and ribose in RNA.

- Each strand of the double helix is held together by covalent bonds between deoxyribose sugar and phosphate groups (on the 3' and 5' carbons) (making up the backbone).

What are pyrimidine/purine and double bonds/triple bonds in DNA structure? In DNA, cytosine (C) is always bonded (i.e. attached) to guanine (G), and thymine (T) is always bonded to adenine (A). This is the general rule. But there are many different types of bonds, namely: single bonds, double bonds, and triple bonds. Just imagine the molecules holding hands.

Polar Covalent Bonds Polar covalent bonds are a particular type of covalent bond. In a polar covalent bond, the electrons shared by the atoms spend a greater amount of time, on the average, closer to the Oxygen nucleus than the Hydrogen nucleus. This is because of the geometry of the molecule and the great electronegativity difference between the Hydrogen atom and the Oxygen atom.

Chemical Bonding a chemical bond. The two extreme cases of chemical bonds are: Covalent bond: bond in which one or more pairs of electrons are shared by two atoms. Ionic bond: bond in which one or more electrons from one atom are removed and attached to another atom, resulting in positive and negative ions which attract each other.Other types of bonds include metallic bonds and hydrogen bonding.The attractive forces between molecules in a liquid can be characterized as van der Waals bonds.ydrogen bonding has a very important effect on the properties of water and ice. Hydrogen bonding is also very important in proteins and nucleic acids and therefore in life processes. The unzipping of DNA is a breaking of hydrogen bonds which help hold the two strands of the double helix together.

- These strong covalent bonds form the the glue that holds the sugar/phosphate backbone together and thus act to keep each strand together. The two strands of DNA are held together by weak hydrogen bonds (remember, something must hold them together!) between the nitrogenous bases.The interesting (and very important) aspect of the Watson-Crick model is that these hydrogen bonds are base specific.hese strong covalent bonds form the the glue that holds the sugar/phosphate backbone together and thus act to keep each strand together.

How Atoms Hold Together Covalent bonding can produce much larger molecules as well. DNA molecules consist of huge numbers of atoms held together mainly by covalent bonds. But there are other ways to hold atoms together. Ionic bonding As an example of another type of bond, let's consider a sodium atom and a chlorine atom.
