Explanation
DNA (deoxyribonucleic acid) stores genetic information. Double helix structure with sugar-phosphate backbone and base pairs inside. Bases: adenine pairs with thymine, cytosine pairs with guanine (A-T, C-G).
Gene is DNA segment coding for protein. Genetic code uses three-base codons specifying amino acids. Transcription: DNA → mRNA. Translation: mRNA → protein at ribosomes.
DNA replication: helix unwinds, each strand serves as template for new complementary strand. Semi-conservative – each new molecule has one old, one new strand. Ensures genetic information passed to daughter cells.
