How do proteins control the characteristics
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. WebSome of these proteins control the cell's internal chemistry. They tell the cell what to do, give the organism its characteristics, and determine the way its body works.
