dna ps modification stability genome editing

Rna editing also rna modification is a molecular process through which some cells can make discrete changes to specific nucleotide sequences within an rna molecule after it has been generated by rna polymerase it occurs in all living organisms and is one of the most evolutionarily conserved properties of rnas. The strength of these technologies stems from the ability to create fractures in the desired region of a specific target sequence as determined by the researcher.
