About This Quiz & Worksheet

The human genome is the term used to describe the DNA content of the cell, and this quiz/worksheet combo will help you test yourself on the concept of the genome and a few related concepts. The practice questions on the quiz will test you on identifying the chromosome count of an organism, the characteristics of chromosome loss, and identifying DNA structures.

Quiz & Worksheet Goals

In these assessments, you'll be tested on:

  • Your ability to determine the chromosome counts of organisms
  • Identifying certain DNA structures
  • Your understanding of chromosome loss and lethal events

Skills Practiced

This quiz and worksheet will allow you to test your skills in the following areas:

  • Reading comprehension - ensure that you draw and retain the most important information on the human genome from the related lesson
  • Defining key concepts - ensure that you can accurately define the DNA structures discussed in this lesson
  • Information recall - access the knowledge you've gained regarding the human genome and DNA structures
  • Knowledge application - use your knowledge of DNA structures and the human genome in order to answer questions about the chromosome counts of given organisms

Additional Learning

To learn more about the human genome, review the accompanying lesson on this topic titled The Genome. This lesson covers the following objectives:

  • Define the genome and chromosomes
  • Define the haploid number and the significance of gametes
  • Discuss homologs, as well as haploid and diploid complements
