PLEASE ANSWER ASAP RNA is a molecule with characteristics and a role similar to DNA. Why is RNA necessary for DNA to fulfill its function?

a. DNA does not contain all the genetic material necessary for a living organism
b. DNA cannot leave the cell’s nucleus, so RNA is needed to bring the code to protein-producing organelle.
c. RNA contains the instructions for how an organism functions and DNA contains the instructions for creating the physical structures of an organism.
d. RNA acts as a checkpoint to ensure that DNA’s code does not contain errors.

Transcription and translation are the means by which cells read out, or express, the genetic instructions in their genes. Because many identical RNA copies can be made from the same gene, and each RNA molecule can direct the synthesis of many identical protein molecules, cells can synthesize a large amount of protein rapidly when necessary. But each gene can also be transcribed and translated with a different efficiency, allowing the cell to make vast quantities of some proteins and tiny quantities of others (Figure 6-3). Moreover, as we see in the next chapter, a cell can change (or regulate) the expression of each of its genes according to the needs of the moment—most obviously by controlling the production of its RNA.

Explanation:

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
