Multiple Choice
The main purpose of DNA is to store information. Where is information stored within a DNA molecule?
A
In the sugar-phosphate backbone
B
In the double helix's helical structure
C
In the sequence of nitrogenous bases (adenine, thymine, cytosine, and guanine)
D
In the hydrogen bonds between the two strands
Verified step by step guidance1
Understand the structure of DNA: DNA is composed of a sugar-phosphate backbone and nitrogenous bases (adenine, thymine, cytosine, and guanine) that pair through hydrogen bonds to form a double helix.
Recognize the role of the sugar-phosphate backbone: The backbone provides structural support but does not store genetic information.
Examine the double helix's helical structure: The helical shape is important for stability and compact storage but does not directly store information.
Analyze the hydrogen bonds between strands: These bonds hold the two strands together but are not the location of genetic information.
Focus on the sequence of nitrogenous bases: The specific order of adenine, thymine, cytosine, and guanine encodes genetic information, as this sequence determines the instructions for building proteins and other cellular functions.
