mRNA is messenger RNA. mRNA is transcribed from DNA, and carries coding information to the ribosomes. Here, the RNA is translated into a protein. In mRNA genetic information i â¦ s encoded in the sequence of nucleotides arranged into codons.o, transcription does not include the use of the ribosomes. This organelle is only used during translation, but not transcription. Transcription is when the mRNA is being mad â¦ e, which is inside of the nucleus, not ribosome. Answered.
