What structure of a protein determines its structure and properties. How is this structure encoded in a DNA molecule?

The properties of a protein are determined primarily by its primary structure, a sequence of amino acids in the polypeptide chain. It is the primary structure that is “recorded” in the gene encoding this protein. Information in the primary structure of the protein is encoded in the DNA molecule in the form of triplets (sections of three nucleotides in the DNA molecule).

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
