A

Unlike in the past, the RNA of today does NOT carry genetic information.

Explanation:

The RNA world hypothesis stipulates that RNA used to store genetic information before the evolution of DNA. RNA, however, is very unstable and it is believed it is the reason for the evolution of DNA which is a more stable form of storing genetic information of cells.

The RNA world hypothesis is supported by the fact that RNA is multifaceted and can also catalyse reactions –like protein enzymes, makes up ribosomes, and can self replicate.
