What is RNA editing and at what level of gene expression does this regulation work?

SUBJECT: Cell Molecular Biology

Most eukaryotic cells transcribe a relatively high portion of their genome, but most of those RNA transcripts are likely not encoding for proteins. Elucidating the function(s) of that "junk" RNA is one of the next big challenges in molecular cell biology. You isolate one of those transcripts and determine that its sequence consists of 50% C, 30% U, and 20% A. What is the percentage of Gs in this transcript?

An important theme in genetics is the central dogma of molecular biology. Who proposed it? Which two processes does it relate to? Explain the processes and indicate where they occur in eukaryotic cells.
