Answer:
Transcription
Explanation:
First comes Transcription, then comes Translation.
For example, DNA comes first, RNA comes second, and Protein comes third which makes proteins last. So, during the DNA process, Replication occurs. After that, DNA hops over to RNA using Transcription, and after that RNA hops over to Protein using Translation. So, we look left to right. Now, when I listed everything, Transcription came first and Translation came second. There is your answer.
