Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Protein molecules are composed of long chains of ____
A
DNA
B
amino acids
C
RNA
D
ribosomes
Explanation: 

Detailed explanation-1: -A protein molecule is made from a long chain of these amino acids, each linked to its neighbor through a covalent peptide bond (Figure 3-1). Proteins are therefore also known as polypeptides. Each type of protein has a unique sequence of amino acids, exactly the same from one molecule to the next.

Detailed explanation-2: -Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein.

Detailed explanation-3: -Protein molecules are long chains of amino acids that are folded into a three-dimensional shape. Chemically, an amino acid is a molecule that has a carboxylic acid group and an amine group that are each attached to a carbon atom called the carbon.

Detailed explanation-4: -A protein consists of one or more chains of amino acids (called polypeptides) whose sequence is encoded in a gene.

Detailed explanation-5: -Proteins are one of the primary constituents of living matter. They consist of long chains of amino acids, which are bonded together by peptide linkages and thus called polypeptides. There are about 20 amino acids, and the atoms most prevalent in these are carbon, hydrogen, oxygen, nitrogen, and sulfur.
