What does transcription do in protein synthesis?

Purpose of Protein Synthesis:

Cells need to do protein synthesis to create new proteins. Proteins are needed for all type of processes inside the cell, from catalyzing chemical reactions to adhering cells to the extracellular matrix and each other. Proteins become worn out over time and new proteins need to be made.

Answer and Explanation: 1

Transcription allows the genetic code to leave the nucleus and serve as the instructions for protein synthesis. Protein synthesis has two main steps, transcription and translation. During transcription, DNA in the nucleus is copied to messenger RNA (mRNA) by RNA polymerase. The mRNA is then processed and leaves the nucleus through the nuclear pores. In the cytoplasm, ribosomes attach to the mRNA and read the code. They use the code to assemble the correct amino acids to create a protein.
