About This Quiz & Worksheet

Use this quiz/worksheet combo to help you test your understanding of the structure of chromosomes. Some of the topics you'll be assessed on include knowing the protein that plays a central role in DNA folding as well as the discrete unit of DNA.

Quiz & Worksheet Goals

In these assessments you'll be tested on:

  • Roles in the cell non-coding DNA could perform
  • Placing terms in order of increasing complexity within the cell
  • Protein that plays a central role in DNA folding
  • Discrete unit of DNA which produces a protein that provides the functionality a cell needs
  • Combination of protein and DNA

Skills Practiced

This quiz and worksheet allow students to test the following skills:

  • Reading comprehension - ensure that you draw the most important information from the related lesson on the structure of chromosomes
  • Interpreting information - verify that you can read information regarding the combination of protein and DNA and interpret it correctly
  • Information recall - access the knowledge you've gained regarding the protein that plays a central role in DNA folding
  • Knowledge application - use your knowledge to answer questions about cellular roles non-coding DNA could perform

Additional Learning

To learn more about cells, review the accompanying lesson on The Structure of Chromosomes. This lesson covers the following objectives:

  • Describe DNA
  • Tell the function of histones and explain how a nucleosome is related to histones
  • Define chromatin and its relationship to chromosome structure
  • Understand the function of DNA and compare/contrast it to the function of non-coding DNA
