How is genetic information stored within DNA? Genetic information is stored within DNA as:

The correct answers are B, C and D.

  • codes of protein reactions
  • a code composed of chemical bases:
    Adenine and Thymine
    Guanine and Cytosine
  • codes of base pairs attached to sugar and phosphate molecules
  • 3 billion base pairs that are about 99% the same in all people
  • None of the above

Genetic information is stored within DNA as a code composed of chemical bases:
Adenine and Thymine
Guanine and Cytosine

DNA bases pair up with each other, A with T and C with G, to form units called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. Together, a base, sugar, and phosphate are called a nucleotide.

Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people. The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences
