About This Quiz & Worksheet

The structure of a protein is based on its sequence of amino acids and how they interact with each other. This quiz/worksheet combo will help test your understanding of the secondary structure of proteins and how 3-dimensional forms in proteins are made. Some concepts you'll be assessed on are common types of secondary protein structures and their functions.

Quiz & Worksheet Goals

In this assessment, you'll be tested on the following:

  • Protein structure with alpha helices
  • Definition and function of an alpha helix
  • DSSP
  • Strands of amino acids packed together like Ramen noodles

Skills Practiced

  • Defining key concepts - ensure that you can accurately define main terms, such as alpha helix
  • Information recall - access the knowledge you've gained regarding the type of protein structure that has alpha helices
  • Distinguishing differences - compare and contrast the structural and functional differences of alpha helices and beta-pleated sheets

Additional Learning

To learn more about protein structure, review the accompanying lesson on Secondary Structure of Protein: Definition & Overview. This lesson covers the following concepts:

  • How beta-pleated sheets are represented in molecular diagrams
  • Eight types of secondary structure listed in the DSSP
  • Cell location where a protein is manufactured
  • The definition of translation
