Adenine pairs with Thymine
Guanine pairs with Cytosine
A shared pair of electrons that holds a chemical bond is called a covalent bond. In a covalent bond, two atoms share electrons to achieve a stable electron configuration. This type of bond is common in nonmetal compounds and results in a strong connection between the atoms involved.
Complementary base pair
Covalent [the sharing of a pair of electrons] bond energy.
In a molecule of hydrogen (H₂), the hydrogen atoms are held together by a covalent bond. This bond forms when the two hydrogen atoms share a pair of electrons, allowing each atom to achieve a more stable electron configuration. The shared electrons create an attractive force between the atoms, effectively holding them together in the molecule.
When one pair of electrons is shared, a single covalent bond exists. This bond can be either polar or nonpolar. If the electrons are equally shared, the bond is nonpolar. If the electrons are unequally shared, the bond is polar.
The nitrogen bases are held together by hydrogen bonds.
The two atoms share their electrons - so it is a covalent bond ie a shared pair.
Guanine and cytosine base pair (triple bond), and adenine and uracil base pair (double bond).
The backbone of the nucleotides are composed of repeating ribose (in RNA) or deoxyribose (in DNA) and phosphates held together by phosphodiester bonds between the 5's and 3's of the ribose/deoxyribose.

A hydrogen molecule is held together by a covalent bond, where the two hydrogen atoms share their electrons in order to achieve a stable electron configuration. This shared pair of electrons creates a bond that keeps the atoms together.
In a single covalent bond, two atoms share a pair of electrons. This shared pair of electrons creates a strong bond that holds the atoms together. The atoms achieve a stable electron configuration by sharing the electrons.
A Lewis base is a molecule or ion that donates an electron pair to another atom to form a covalent bond. It is a species that can provide a pair of electrons to form a new bond. Lewis bases are electron-pair donors.
there is repulsion between lone pair and bond pair for example in water molecule oxygen has lone pair which repells the bond pair due to this bond angle decreases simply ddue to repulsion btween lone pair to lone pair or lone pair to bond pair angle varies
I think you mean a covalent bond. It is a shared pair of electrons which joins atoms together.
