There are a few reasons. Primarily DNA is found in the nucleus, whereas the translation process is carried out by ribosomes in the cytoplasm. Therefore it is necessary to have some kind of messenger that allows for the DNA code to be translated into proteins. This messenger is known as messenger RNA (mRNA).
In the process of transcription, DNA is used as a blueprint to make m-RNA which codes for a specific protein.
mRNA carries the code that was transcribed from DNA out to the ribosome to form the correct amino acid chain. So, yes, in a way mRNA is a messenger to the ribosomes since DNA cannot leave the nucleus.
RNA is necessary to act as a messenger because it carries genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm, where proteins are synthesized. It serves as a temporary copy of the genetic code, allowing the cell to produce proteins based on the instructions encoded in the DNA.
mRNA (messenger RNA) carries the message of DNA to ribosomes. It serves as the intermediary molecule that transfers genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm where protein synthesis occurs.
Messenger RNA (mRNA) is a copy of the DNA message that is transcribed in the nucleus and can be translated into proteins in the cytoplasm. It carries the genetic information from the DNA to the ribosomes where protein synthesis occurs.
RNA is necessary to act as a messenger because it carries the genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm, where proteins are synthesized. It serves as a template for protein synthesis and helps in decoding the genetic information stored in the DNA. RNA is also more versatile and can move in and out of the nucleus, facilitating the efficient transfer of genetic information.
DNA contains the information on how to make proteins. This information is stored in the form of genes, which are sequences of nucleotides within the DNA molecule. Genes are transcribed into messenger RNA (mRNA), which is then translated into proteins by ribosomes.
RNA (Ribonucleic Acid)...this is the messenger of the DNA (Deoxyribonucleic Acid) The RNA carries directions from the DNA to the Ribosomes that tell the Ribosomes what protein to make and how to do it. RNA reads the blueprint (DNA)
B. RNA. The information necessary to direct the cell is contained in the cell's RNA, specifically messenger RNA (mRNA), which carries genetic information from the DNA in the nucleus to the ribosomes where proteins are synthesized.
Dna transcription, the production of messenger Rna.

mRNA is synthesized from a DNA template during transcription
