Organisms make one type of protein for a feature while other organisms

make two as a result of difference in structure and functions .Proteins are

referred to as compounds with unique nucleotide sequences which gives

rise to unique structures and functions.

Protein is regarded as the building block of life and it contains amino acids

which have unique nucleotide sequences.These sequences are responsible
