About This Quiz & Worksheet

These quiz questions are designed to put your knowledge of the genetic code to the test. You'll be asked questions about the bases of DNA and RNA, codons, genetic code sequences and codon transfers.

Quiz & Worksheet Goals

The practice quiz will ask you to:

  • Know the amount of DNA and RNA bases
  • Identify RNA bases
  • Understand codons and their bases
  • Identify correct genetic code sequences
  • Name the amount of amino acids used in codon transfers

Skills Practiced

You'll practice the following skills:

  • Information recall - access knowledge you've gained about RNA and DNA bases
  • Knowledge application - use your knowledge of genetic code bases to recall how many bases are in DNA and RNA
  • Making connections - be able to assess examples of the genetic code process and identify the correct sequence

Additional Learning

To get more information on this concept, watch the related lesson, Overview of the Genetic Code. The lesson goes over the following objectives:

  • Learn how the genetic code works
  • Understand how many base combinations exist for codons
  • Identify what letters are used for codons
