During protein synthesis peptide bonds are formed between the amino acids. Each codon on m-RNA consists of three nucleotides (triplet). A complementary antocidon is carried by t-RNA molecule.

Coordinate bond is a covalent bond in which the shared pair of electrons is contributed by one of the atoms only. A coordinate bond is denoted by an arrow (→) pointing towards the acceptor atom.
A chemical bond may be defined as the chemical force that keeps all the atoms in any molecule together. The combining atoms acquire stable electronic configuration either of the following three ways.
An ionic (or electrovalent) bond is formed between two ions of opposite charges. During the formation of an ionic bond, one of the reacting elements should form a positively charged ion (cation), and the other should give a negatively charged ion (anion).
Covalent bond is formed due to mutual sharing of electrons by the combining atoms. The shared pair of electrons lies between the two nuclei. Both the nuclei attract the shared pair of electrons. The shared pair of electrons thus keeps them together, and a stable bond is formed.
A coordinate bond is a covalent bond formed between two atoms in which the shared pair of electrons is contributed by only one of the atoms. The atom providing the electron pair is called the donor atom.
The chemical bond formed by the sharing of electrons between two atoms is known as a covalent bond. The sharing of electrons takes place in such a way that each atom in the resulting molecule gets a stable configuration.
