Summary

Every cell in an individual has a unique chromosome complement, with 20 000–25 000 genes coded into a DNA sequence of 3 billion base pairs, packed into 23 pairs of chromosomes: a total of 46 chromosomes in each diploid human cell. All of these cells have the same genetic information, copied during mitotic divisions by replicating the DNA during each cell cycle. The pattern of gene activity in each cell (gene expression/transcription) dictates its function and fate, enabling different cells to differentiate and carry out distinct functions.
