The primary structure of a protein refers to the sequence of amino acids that
are linked together in a long chain. Which of the following common items
would best represent the primary structure of a protein?
O
A. A dry kitchen sponge sitting beneath a mound of table salt
O
B. Beads of different colors joined together on a piece of string
O
C. A burning wax candle placed in front of a small fan
O
D. Two unsharpened pencils held together by a piece of tape

Respuesta :

B. Beads of different colors joined together on a piece of string.

Explanation:

In a primary structure of protein the smaller subunits amino acids are linked by peptide bonds.

The peptide bond is formed when carboxyl or C=O group of amino acid bonds with NH2 of the other amino acid, releasing water molecule.

This process of peptide bond formation is called condensation.

The long string of bead represents different amino acids formed in the ribosome. All amino acids are arranged in the linear chain of  primary protein structure hence resemble a string of beads.

The primary structure undergoes further modifications and changes in the Golgi Complex of the cell, as folding and modification of amino acid chain formed by the process of translation.
