RNA editing is when an RNA molecule is changed (edited) through a chemical change in the base make up. There are various types of RNA editing - namely insertions/deletions and switching bases like Cytidine to Uridine or Adenosine to Inosine (properly known as deamination).
RNA editing has been observed in tRNA, rRNA and mRNA (interestingly enough all of them have to do with protein synthesis) of eukaryotes (in the cell nucleus, cytosol, mitochondrion, and chloroplast) but not in prokaryotes - which is interesting because both the mitochondrion and chloroplast are believed to be descended from prokaryotes.
RNA editing take place in order to insure that only the codons that code for a particular gene will be translated into a protein.
This is True! RNA editing is different than pre-mRNA processing, which takes place in the nucleus: Processing includes the removal of the introns (splicing), cleavage at the poly A site, and poly-adenylation. Then RNA translation is effected at the Cytoplasmic Ribosomes.RNA editing, which is different, has been shown to occur in the cytosol, the nucleus, and inside the mitochondria.
No. The process which eliminatesintrons is called 'splicing'. This process is mediated by the protein complex called a spliceosome and probably occurs simultaneously with RNA editing. RNA editing is the addition, removal or substitution of bases in an RNA molecule after it has been synthesised, and critically can occur in organisms which lack introns. There are 3 main types of RNA editing: 1, Addition or removal of Uracil residues. Seen in the primary transcripts in trypanosome mitochondria (does not appear in multicellular organisms). 2, Cytosine -> Uracil Editing. Seen in mRNAs in some animals and plant mitochondria. 3, Adenosine -> Inosine. Seen in animal mRNAs. (Inosine is a very rare base which you get from the deamination of adenosine)

To make RNA
Reverse transcriptase is the viral enzyme responsible for making a DNA copy of the RNA genome from a retrovirus. As such, it is technically known as an RNA-dependent DNA polymerase. This is opposite to the usual flow of genetic information from DNA to RNA to protein. This allows a virus with an RNA genome to make copies of itself that can be integrated into the DNA of its host.

In a DNA extraction, the purpose of a buffer is to solubilize DNA as well as RNA. Because of this, it prevents the DNA for degrading.
Yes, you can undoubtedly ask for help in editing your dissertation. There is multiple dissertation help services available for the purpose of editing. Out of all the services in the field, my favorite one is of Home of Dissertations, as they have very expert and experienced editors in their team.
