Explain how each of the following processes complicates the concept of colinearity.
Q. RNA editing
Some RNA molecules are altered after transcription to produce bases not encoded in the genome. This most commonly involves the editing or alteration of one base to another but can require the addition or deletion of a base in certain species. The coding properties of mRNA are altered by such editing activities.
RNA editing can be generally characterized by nucleotide deletion, insertion, or base modification mechanisms as the co- or post-transcriptional modification of the primary sequence of RNA from that encoded in the genome. The RNA editing processes are known to create diversity in proteins involved in various pathways like lipid transport, metabolism etc.
