Explanation:

In gene expression, transcription occurs first. It is the process of copying DNA into RNA. Translation then uses that RNA to make proteins. These processes are crucial as they convert genetic information (DNA) into functional proteins. Proteins perform most cellular functions, from catalyzing reactions (enzymes) to providing structure. Without transcription and translation, cells couldn't produce the proteins needed for life - processes like metabolism, growth, and responding to the environment would fail.

Answer:

Transcription happens first. These two processes are important because they convert genetic information (stored in DNA) into proteins. Proteins are essential for almost all cellular functions, including catalyzing biochemical reactions (as enzymes), providing structural support, enabling cell signaling, and facilitating transport across cell membranes.
