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.
