The correct option is mRNA.
mRNA stands for messenger RNA. For protein to be synthesized inside the cell, the genetic information inside the DNA has to be transcribed into the mRNA, which will move out of the nucleus and carry the information to the ribosomes. During the process of protein synthesis, the genetic information transcribed into the RNA will be used to produce new proteins.
Messages are slower acting and longer lasting. Plus they are classified as hormones, transported in the blood.
the four molecules of life are proteins, carbohydrates, lipids and nucleic acids. Each of the four groups is vital for every single organism on Earth. Without any of these four molecules, a cell and organism would not be able to live. All of the four molecules of life are important either structurally or functionally for cells and, in most cases, they are important in both ways.
