what protein structure is shown below? *\nprimary\nsecondary\ntertiary\nquaternary
Answer
Answer:
B. secondary
Brief Explanations:
Protein secondary structure involves local folding. Common forms are alpha - helices (like the coiled structure) and beta - sheets (like the zig - zag structure). Primary is the amino acid sequence. Tertiary is overall 3D shape. Quaternary is multiple subunits. Since the image shows alpha - helices and beta - sheets, it's secondary.
