How is the hereditary information in DNA coded and pasesed from generation?

Hereditary information in DNA is coded through sequences of nucleotides, which consist of four bases: adenine (A), thymine (T), cytosine (C), and guanine (G). These sequences form genes, which provide instructions for building proteins essential for various biological functions. During reproduction, DNA is replicated and passed from parents to offspring, ensuring the transmission of genetic traits. This process occurs through meiOSis in sexual reproduction, leading to genetic variation, while asexual reproduction relies on mitosis to produce genetically identical offspring.
