Reality Check

Genes encode for proteins. Polypeptides are proteins.

What is the relationship between genes and the polypeptides?

Proteins are made of polypeptides. Polypeptides are strings of peptides which are groups of amino acids and are thus the structural units of proteins.

Genes are segments of DNA that code for the production of a particular protein which is in turn responsible for a particular trait.

During the processes of transcription and translation, the protein information from a specific gene is transcribed onto messenger RNA. This mRNA code leaves the cell's nucleus and travels to ribosomes in the cytoplasm where the mRNA code is translated to form a chain of specifically ordered polypeptides. These polypeptide chains then form a protein.

Therefore, indirectly, genes lead to the formation of specific polypeptide chains.

Hope this helps :smile:
