The answer is : DNA<span> is a long polymer with deoxyriboses and phosphate backbone. Having four </span>different<span> nitrogenous bases: adenine, guanine, cytosine and thymine. </span>RNA<span> is a polymer with a ribose and phosphate backbone. Four </span>different<span> nitrogenous bases: adenine, guanine, cytosine, and uracil. Hope this Helps! Good Luck!</span>
Deoxyribonucleic acid acts as the genetic material of almost all the living organisms. The deoxyribose pentose sugar is present in its DNA structure. The nitrogenous bases present in DNA are adenine, guanine, thymine and cytosine. DNA is highly stable in nature and cannot acts as the catalyst.
RNA:
Ribonucleic acid acts as the genetic material in case of few viruses only. The oxyribose pentose sugar is present in RNA structure. The nitrogenous bases present in RNA are adenine, guanine, cytosine and uracil. RNA is highly unstable in nature and acts as a catalyst.
I would say Option B) because Option C) is wrong since matter cannot be created. A closed system does not exchange matter so it's not Option D). Since an island is an isolated area, Option A) is wrong.
