This is a two part process that ends in the a simile a proteins at the ribosomes within cell. the first part transcription begins in the nucleus when the dna code is transferred to the mrna. the second part translation takes place at the ribosomes where both mrna and trna work to assemble proteins

The first part, transcription, begins in the nucleus, when the DNA code is transferred to mRNA. The second part, translation, takes place at the ribosomes, where both mRNA and tRNA work to assemble proteins. A biological catalyst. Anabolic enzymes build up, Catabolic enzymes break down.
