Why RNA Editing?
Good question. Some possibilities:
Perhaps — like alternative splicing — it is a mechanism to increase the number of different proteins available without the need to increase the number of genes in the genome.
An RNA virus is a virus that either uses RNA as its genetic material, or whose genetic material passes through an RNA intermediate during replication.

Definition of RNA :
A single-stranded nucleic acid similar to DNA but having ribose sugar rather than deoxyribose sugar and uracil rather than thymine as one of the pyrimidine bases.
An enzyme that catalyzes the synthesis of an RNA strand from a DNA template. The enzyme that polymerizes RNA by using DNA as a template. It can also act as a primase initiating DNA replication. (Also known as transcriptase or RNA transcriptase).
Transfer RNA is that key link between transcribing RNA and translating that RNA into protein.
Mature transcript of RNA splicing which removes introns and joins exons in the primary transcript. mRNA usually has a 5' UTR, 3' UTR and polyA.

Entry of the Viral RNA
Tight attachment of the viral particle to receptors on the lymphocyte membrane enables fusion with the cell membrane. The viral contents, including viral RNA (shown in yellow) then empty into the cell's cytoplasm.
RNA links the information in DNA to the sequence of amino acids in protein
During the 1930s, despite great advances, geneticists had several frustrating questions yet to answer:
What exactly are genes?
RNA polymerase recognizes a specific base sequence in the DNA called a promoter and binds to it. The promoter identifies the start of a gene, which strand is to be copied, and the direction that it is to be copied.
RNA -- "ribonucleic acid". The nucleic acid which carries the DNA message into parts of the cell where it is interpreted and used. The 18S ribosomal RNA sequence has been used in many groups of organisms to reconstruct phylogeny.
RNA, ribonucleic acid (RYE-bo-new-CLAY-ick) A molecule very similar to DNA that plays a key role in making proteins.
RNA polymerase During transcription, an enzyme that attaches to the promoter region of the DNA template, joins nucleotides to form the synthesized strand of RNA and detaches from the template when it reaches the terminator region. PICTURE ...

RNA (ribonucleic acid). An organic acid composed of re- peating nucleotide units of adenine, guanine, cytosine, and uracil, whose ribose components are linked by phosphodiester bonds.
RNA primers Small pieces of RNA that base-pair with the template strand of DNA and serve as primers for primer-dependent DNA synthesis; the RNA is later removed and replaced by DNA.

Using these programs to find ORFs in bacterial genomes is relatively easy. Here, the DNA sequence matches the mRNA. The situation is more complicated for eukaryotic genes, which often contain one or more noncoding regions (introns).

The most important part is a small piece of DNA or RNA (never both). That strand of nucleic acid is considered the core of the virus. The second big part is a protein coat to protect the nucleic acid. That coat is called the capsid.

Therefore each strand of DNA or RNA has a free 3' C at one end and a free 5' C at the other. The free 3' C normally carries a - OH group, and the 5' C a phosphate group.
Polymerase, DNA or RNA Enzymes that catalyse the synthesis of nucleic acids on preexisting nucleic acid templates, assembling RNA from ribonucleotides or DNA from deoxyribonucleotides.
The common ancestor of all life probably used RNA as its genetic material. This ancestor gave rise to three major lineages of life.
Most viruses maintain all their genetic information with the single-stranded RNA. There are two types of RNA-based viruses.
Cells transcribe a DNA gene into an RNA version of the gene, and a ribosome then translates the RNA into a protein, a sequence of amino acids.
Viruses are inert beings because they are simple particles of nucleic acids (RNA or DNA) wrapped by a capsule of protein that cannot experience life.
In situ hybridization Use of a DNA or RNA probe to detect the presence of the complementary DNA sequence in cloned bacterial or cultured eukaryotic cells.
In vitro Studies performed outside a living organism such as in a laboratory.
Nucleotide: A subunit of DNA or RNA composed of a nitrogenous base, a phosphate molecule, and a pentose sugar molecule.
Pentose sugar: A sugar molecule containing five carbon atoms. E.g.: deoxyribose.

A second meaning refers to cloning DNA, or the act of creating copies of an individual gene, for expression in a foreign host, which leads to generation of exact replica macromolecules (e.g. DNA, RNA, proteins).
4. How do Buffers Work?
Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interrelationship of DNA, RNA and protein synthesis and learning how these interactions are regulated.
