Question

Quizplus · Accepted Answer

RNA is capable of self-replication, which is thought to have been the first step in the development of genetic material. This ability to copy itself without the help of enzymes or other proteins is considered a crucial aspect in the origin of life.

Answer: D 
 Some primitive organisms, such as some viruses, have RNA as their genetic material. It is believed that early life forms may have used RNA as their genetic material before the emergence of DNA. However, it should be noted that this is a hypothesis and not a proven fact. The other options are not relevant to the question.
