Explain how genes are expressed for a particular trait.

Answer:

Gene expression begins with the process of transcription, where a specific gene for a trait is transcribed from DNA into messenger RNA (mRNA). This mRNA then travels to a ribosome. During translation, the ribosome uses the mRNA code to assemble a polypeptide chain of amino acids. Once this polypeptide chain is completed and folded into a functional protein, the trait is expressed.
