Is DNA is a protein

Answer 1

No. Proteins are made of long chains of amino acids. DNA is made of long chains of only four nucelotides: adenine, thymine, guanine, and cytosine.

Answer 2

Yes it is. It is an enzyme and therefore a complex polypeptide, otherwise known as a protein.

"Enzymes are biomolecules that catalyze (i.e., increase the rates of) chemical reactions.[1][2] Almost all enzymes are proteins. In enzymatic reactions, the molecules at the beginning of the process are called substrates, and the enzyme converts them into different molecules, called the products. Almost all processes in a biological cell need enzymes to occur at significant rates. Since enzymes are selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell."
