Unveiling the Secrets of DNA Structure

All cells require DNA as instructions for proper function.

DNA contains the code for making proteins and determines inherited characteristics.

DNA is composed of repeating units called nucleotides, which consist of a phosphate group, a sugar, and a nitrogen base.

🔍 DNA is composed of four bases: thymine, adenine, cytosine, and guanine.

⚛️ There are two types of bases: purines (adenine and guanine) and pyrimidines (cytosine and thymine).

📜 The structure of DNA is a double helix with a spiral shape, formed by the pairing of bases.

🔑 The structure of DNA consists of nitrogen bases, such as Adenine, Thymine, Guanine, and Cytosine, which form hydrogen bonds together.

🔑 Adenine always pairs with Thymine, and Guanine always pairs with Cytosine, based on the number of hydrogen bonds they form.

🔗 The complementary strand of DNA can be predicted based on the knowledge of the other strand, as they are always paired together.

🧬 The structure of DNA consists of Deoxyribose sugars and phosphates, which make up the outside of the molecule.

🧬 Deoxyribose and phosphate are key components of DNA structure.

🔢 Nucleotides with two hydrogen bonds are paired with A and T, while those with three are paired with C and G.

🔍 Pyrimidines have one ring, while purines have two, determining the pairing of cytosine, thymine, adenine, and guanine.
