Is dna a polypeptide
WebJul 18, 2024 · Polypeptides and Proteins The result of protein synthesis is a chain of amino acids that have been attached, link by link, in a specific order. This chain is called a polymer or polypeptide and is constructed according to a DNA-based code. You can picture a polypeptide chain as a string of beads, with each bead playing the part of an amino acid. Webd. RNA polymerase transcribes through the polyadenylation signal, causing proteins to associate with the transcript and cut it free from the polymerase. c. RNA polymerase transcribes through the terminator sequence, causing the polymerase to separate from the DNA and release the transcript.
