A hydrogen bond.
Nitrogen bases bond through hydrogen bonds. Nitrogen is a chemical element and is odorless and colorless. It's atomic number is 7.
A hydrogen bond--two between A and T and three between G and C.
A polar molecule is positive on one end and negative on the opposite end. A hydrogen bond is a special attraction between polar molecules, a weak bond.
There is no chemical bond as such between lipid bi-layers. A chemical bond would not allow the membrane to be flexible and dynamic. The two layers are held together through hydrophobic interactions
if the order of nitrogenous bases is mixed up the chemical reactions will be the wrong result. they are set in a specific order for a reason Adenine pairs with Thymine(Double bond) Guanine pairs with Cytosine (Triple Bond) A & G are purine bases and T & C are pyrimidine bases. this is the order
hydrogen bonds, which are very easy to break.
Covalent bond exists
Covalent bond exists between a carbon atom and a chlorine atom.
The chemical bond between chlorine and hydrogen is polar covalent.
Single covalent bond :)
The connection between two atoms is chemical bond. This is used in science.
Hydrogen bond
is the line between elements in a chemical bond
It is called a "metallic bond"
Peptide bonds.
The chemical bond in silver is a metallic bond.
It is a single covalent bond.
