What are adenine, thymine, cytosine, and guanine?
This is the main job of DNA in living organisms.
What is storing and transmitting genetic information?

What are adenine and guanine?
This is the name of the basic building block of DNA.
What is a nucleotide?
These two nitrogen bases have one ring and are called pyrimidines.
What are cytosine and thymine?
This structure contains instructions that help determine a specific trait.
What is a gene?
This is the number of hydrogen bonds between adenine and thymine.
What are two?
This structure is made up of DNA and contains genetic information.
What is a chromosome?
This is the number of hydrogen bonds between cytosine and guanine.
What are three?
