Question
What is the building block of DNA
- Monosaccharide
- Amino Acid
- Fatty Acid
- Nucleotide
Hint:
DNA is made up of nucleotides like adenine, guanine, cytosine, and thymine.
The correct answer is: Nucleotide
- DNA is a molecule made up of nucleotides.
- The nucleotides are four chemical bases: adenine (A), cytosine (C), guanine (G), and thymine (T).
- For the two strands of DNA to zip together, A pairs with T with a double bond, and C pairs with G with a triple bond.
