Indicate at which step of the replication-transcription-translation process each type of RNA first plays a role.
Transcription/RNA processing: mRNA
Translation: tRNA, rRNA
During replication, a faithful copy of a DNA molecule is made.
During transcription, the DNA "message" is copied onto a molecule of mRNA.
During translation, the information carried in the mRNA is transferred to molecules of tRNA to build a protein on the ribosomes.
The steps at which the specific kind of RNA plays role is determined by the information carried by the RNA for several cellular processes.
The process of transcription and RNA processing is done by mRNA (messenger RNA). Translation is done by tRNA (Transfer RNA) and rRNA (Ribosomal RNA). During replication, a same copy of a DNA molecule is produced while during transcription, the DNA sequence is copied onto a molecule of mRNA. Translation is the process by which RNA produces proteins of specific kind. The information about the kind of protein is given by mRNA.
