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.

What is meant by signal transduction and what is its effect on the process of egg activation?
kotegsom [21]

Answer:

The process by which a cell responds to substances outside the cell through signaling molecules found on the surface of and inside the cell. ... Signal transduction is important for cells to grow and work normally. Cells that have abnormal signaling molecules may become cancer cells. Also called cell signaling.

Egg activation, whether initiated by or independent of fertilization, induces a rise in intracellular calcium. This calcium increase often manifests as a signaling wave that traverses the egg and releases it from meiotic arrest and metabolic dormancy.
