Study Notes
DNA Structure
- DNA contains 4 different nucleotide bases: Adenine, Guanine, Cytosine, and Thymine
- Thymine is paired with Adenine (T-A) through 2 hydrogen bonds
- Nucleotides form 2 complementary strands, according to the model proposed by James Watson and Francis Crick
- The fifth carbon in a nucleotide is the site of attachment for a phosphate group
Test your knowledge of DNA structure with this quiz! Explore the basic components of DNA, including nucleotides and their three key elements: 5 carbon sugar (deoxyribose), phosphate group, and nitrogenous bases (adenine, thymine, cytosine, guanine). Delve into the distinct characteristics of the four different nucleotides found in DNA and enhance your understanding of their unique properties.
