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.

<u>Sensory</u> memory.

Explanation:

Sensory memory is the type of memory that stores information for a very brief period of time it is even shorter than the time period of  the short term memory.

Sensory memory helps the  brain to hold the effects  of a sensory stimulus for sometime  even after the stimulus has ceased. This helps in continuous perception and processing of data in the brain.

The  expression of continuous reading, writing and speaking are due to the existence of sensory memory.

If sensory memory does not function properly then, the synchronization of words and their understanding would have been impossible.
