Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How are amino acids held together?
A
By the centromere
B
By the peptide bond
C
By the metaphase plate
D
By the nucleus
Explanation: 

Detailed explanation-1: -Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.

Detailed explanation-2: -Answer and Explanation: Amino acids are held together by an amide bond, which is also called the peptide bond. Each amino acid has an amine group attached to an alpha carbon that is also attached to a carboxylic acid group.

Detailed explanation-3: -A peptide is a short chain of amino acids. The amino acids in a peptide are connected to one another in a sequence by bonds called peptide bonds.

Detailed explanation-4: -The amino group of one amino acid interacts with the carboxyl group of another amino acid and releases a water molecule as two amino acids are covalently bound by a peptide bond.

Detailed explanation-5: -A peptide bond is a chemical covalent bond that joins amino acids together to form proteins. A peptide bond occurs between a carbon atom of one amino acid with a nitrogen atom of the other amino acid by removing a hydroxyl group and a hydrogen atom to form a molecule of water.
