Question

An example of natural biopolymer is:
A) Teflon
B) Nylon-6,6
C) Rubber
D) DNA

Answer 1

Hint: The answer to this question relies upon the sentence given in the question as bio polymer which means that it is naturally synthesized and has the biological process where this polymer plays an important role in the biological process.

Complete step by step answer:
We have studied the facts in the biochemistry part which includes the chapters of the enzymes and also the chemicals that are indulged in the biological functioning of all the living creatures on the earth.
We shall now see what the biopolymer means and also several instances relating to it that help us to guess the correct answer.
- Biopolymers are those polymers which are produced naturally by the cells of living organisms.
- Some of the biopolymers formed are polypeptides, polysaccharides, polynucleotides and so on.
- DNA is the naturally synthesized biopolymer inside the body of a living organism and also several others include collagen, starch, cellulose, gelatine etc.
- DNA is the natural polymer which is made of the monomer units called as the nucleotides.
- Teflon and nylon – 6,6 are the synthetic polymers that are man - made and rubber is naturally produced by plants.

Therefore, the correct answer is option D. DNA

Note: Note that even if rubber is the naturally available polymer that is synthesized by the plants but it is not a biopolymer because it is not synthesized inside the body of living organism and thus this difference of natural polymers and natural biopolymers will help you to differentiate the given questions and leads you to the correct answer.
