The diagram shows the process of transcription of gene for making proteins.

The diagram shows a process that occurs in eukaryotic cells is transcription of gene for making proteins because the diagram represents the structure of DNA. Transcription is the process of making an RNA copy of a gene sequence. This copy is known as messenger RNA (mRNA) molecule.

This messenger RNA leaves the cell nucleus where it is produced and enters the cytoplasm where it directs the synthesis of protein which it encodes so we can conclude that the diagram shows the process of transcription of gene for making proteins.

explanation:

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
