Primary Structure

Primary Structure
The primary structure of a protein is its linear sequence of amino acids and the location of any disulfide (-S-S-) bridges.

The primary structure is the sequence of amino acids.

The primary structure of a protein simply [is] the linear amino acid sequence-you could write down on a piece of paper the primary structure of a protein.

The sequence of amino acids is called its primary structure (the bonds between the amino acids are called peptide bonds) and the sequence is determined by the genetic code.

Amino acids are linked together into a polypeptide, the primary structure in the organization of proteins.

multiple forms of enzymes arising from genetically determined differences in primary structure. The term does not apply to those derived by modification of the same primary sequence.

The sequence of codons in the mRNA unambiguously defines the primary structure of the final protein. Of course, the codons in the mRNA were also present in the genomic DNA, but the sequence may be interrupted by introns.
