The simple answer is that DNA is located in the cell nucleus, but protein synthesis takes place in the cytoplasm. So a messenger molecule (mRNA) is needed to carry the genetic information from DNA (in the nucleus) to the ribosomes (in the cytoplasm) where the proteins are synthesised. See: http://www.phschool.com/science/biology_place/biocoach/transcription/tctlpreu.html
RNA acts a messenger molecule because it carries information from the DNA in the nucleus to the ribosomes in the cytoplasm. This appears to have evolved over millions of years to occur in eukaryotic cells, although the advantages are not well understood. In the early stages of life on planet Earth, it appears that RNA was both the genome and the messenger, possibly at the same time.
RNA is called a messenger because it transports genetic material to the cytoplasm.
Look...RNA and RNA messenger...RNA are both the same.
Rna was the original Genetic material; it became superceded by Dna yet it ended up performing an astoundingly complex set of functions - m Rna, t Rna, r Rna, et al...
DNA code is copied to messenger RNA, abbreviated mRNA.
This is called messenger RNA. mRNA
Molecules of Ribonucleic Acid (RNA) carry the instructions for assembling proteins out of the cell nucleus. Without this type of molecule, the cell cannot survive.
mRNA (messenger RNA)
The process wherein messenger RNQ (or mRNA) is given a message is called transcription. In this process, n mRNA molecule is made (or transcribed) using DNA as the template. Essentially, the nucleotide sequence on a gene is read by an enzyme called RNA polymerase which synthesizes the mRNA molecule. Put simply, RNA polymerase scans the length of DNA until a gene is encountered. When the enzyme reaches the correct position, it begins adding complimentary nucleotides to make the mRNA molecule. This way, the entire gene is transcribed and copied on to the mRNA molecule.

messenger RNA, mRNA
During transcription a protein molecule called a messenger RNA, or mRNA, is produced. This protein becomes important later during translation.
The mRNA carries information to the ribosomes. This is known as 'messenger' RNA because it carries the message, the base sequence from the nucleus to the ribosome. This mRNA is then translated into an amino acid sequence (polypeptide/protein) at the ribosome.

mRNA (messenger RNA)
Amino acids are the basic units of messenger RNA. mRNA is synthesized from DNA and is a single stranded molecule.
