Answer:
<h2> Replication: DNA  into DNA, and RNA primer are required;</h2><h2>Transcription/RNA processing: pre mRNA and then mRNA;</h2><h2>Translation: tRNA, rRNA</h2>
Explanation:
1. During replication,  a semi-conservative copy of a DNA molecule is made with the help of various enzymes and RNA primer.
2. Transcription/RNA processing: mRNA
During transcription, the DNA "message" ( in the form of codon) is copied into  mRNA.
3. Translation: tRNA, rRNA
During translation, the information carried in the mRNA is translated into protein with the help of molecules of tRNA and rRAN to build a protein on the ribosomes.
