Question

What is the spiral shape of a coiled protein created by a polypeptide chain that intertwines with each other?

1) Alpha helix
2) Beta sheet
3) Random coil
4) Turn

Answer 1

The spiral shape of a coiled protein created by a polypeptide chain that intertwines with each other is called an alpha helix.

Step-by-step explanation:

The spiral shape of a coiled protein created by a polypeptide chain that intertwines with each other is called an alpha helix. In the alpha helix, the polypeptide chain acquires a coil shape spiraling clockwise from N-terminus to C-terminus, held by hydrogen bonds between the carbonyl groups and amine groups in the backbone.
