c) expression of genes and production of specific proteins.
Explanation:
Estrogen is a lipid-soluble steroid hormone that diffuses through the lipid bilayer of the plasma membrane of its target cell. The hormone binds to its nuclear receptor and receptor-hormone complex then alters the expression of particular genes.
It triggers transcription of specific DNA sequences into mRNA which in turn enters the cytoplasm and serves as a template for synthesis of specific proteins.
Estrogen is the female sex hormone and stimulates development of secondary sexual characters in females as well as required for maturation of egg.
