WebThe gene's sequence is like language that instructs cell to manufacture a particular protein. An intermediate language, encoded in the sequence of Ribonucleic Acid (RNA), translates a gene's message into a protein's amino acid sequence. It is the protein that determines the trait. This is called central dogma of life. WebMay 9, 2024 · How does gene expression and proteins control inherited traits? For a gene to be expressed, a protein will bind to the promoter region, telling the cell to transcribe the DNA into RNA. The messenger RNA will go to a ribosome and provide the directions for translation, or making a protein.
