Nitrogen bases bond by the help of covalent or hydrogen bonds
They bond via Hydrogen Bonds.
triple bond between the nitrogen atoms
Covalent bond
Nitrogen and bromine will form a covalent bond; they are both nonmetals.
Covalent bond
A ionic bond
Nitrogen bases bond through hydrogen bonds. Nitrogen is a chemical element and is odorless and colorless. It's atomic number is 7.
Hydrogen bond
Adenine and thymine bond,cytosine and guanine bond
The two chains are connected by hydrogen bonding between nitrogen bases to form a long double-stranded molecule.So hydrogen bonding determines which nitrogen bases form pairs of DNA.
the deoxyribose sugar
Adenine pairs with Thymine(Double bond) Guanine pairs with Cytosine (Triple Bond) A & G are purine bases and T & C are pyrimidine bases.
chromosomal defect
The nitrogen bases bond A-T and C-G via hydrogen bonds. The bases are held together in the string by a backbone of alternating phosphate and sugar molecules.
A weak hydrogen bond, adenine and thymine have a double hydrogen bond cytosine and guanine have a triple hydrogen bond
The nitrogen bases are held together by hydrogen bonds.
Nitrogen is not a bond; it is the single element Nitrogen.
This bond is covalent.
