Discover what makes up the rungs of the DNA molecule: nitrogenous base pairs (A-T and C-G) held by hydrogen bonds. Learn about base pairing rules, hydrogen bonding, and why the structure is vital for genetics. Includes FAQs and real-world applications.

Understand the three essential components of every nucleotide: nitrogenous base, sugar, and phosphate group. Learn how these parts define DNA vs RNA, drive cellular energy (ATP), and enable genetic coding. Essential for biology students and enthusiasts.

Discover where DNA is found in different cell types: nucleus (animals/plants), mitochondria, chloroplasts (plants), and nucleoid (bacteria). Learn why location affects inheritance, disease, and biotechnology applications. Includes DNA visualization methods.

Discover where the information for protein synthesis is stored in cells. Learn how DNA holds genetic blueprints for proteins, the transcription-translation process, mutation impacts, and real-world applications in medicine and genetics.
