Answer:
Gene regulation
Explanation:
Gene regulation refers to the process which controls the expression of the genes present on the chromosomes.
The process is a complex mechanism which involves the structural changes in the genes like the methylation uncoils the DNA from the nucleosome, the binding of specific molecules which could activate the process of transcription and translation.
All these changes lead to the expression of genes and thus gene expression leads to the formation of proteins.
Thus, Gene regulation is the correct answer.
