Using RNA as a template for protein synthesis instead of translating proteins directly from the DNA is advantageous for the cell because
A)RNA is much more stable than DNA.
B)RNA acts as an expendable copy of the genetic material.
C)only one mRNA molecule can be transcribed from a single gene, lowering the potential rate of gene expression.
D)tRNA, rRNA and others are not transcribed.
E)mRNA molecules are subject to mutation but DNA is not.

RNA can act as an expendable copy of DNA, allowing for easier regulation and modification of gene expression. Transcribing RNA also allows for the removal of non-coding regions and alternative splicing, leading to greater diversity of protein products. RNA stability, potential rate of gene expression, and mutation susceptibility do not provide advantages for using RNA as a template for protein synthesis. tRNA and rRNA are actually transcribed from DNA into RNA, and are essential for the process of protein synthesis.
