DNA molecules control the appearance and functions of a cell by encoding the instructions for building proteins, which are essential for cellular structure and activity. Genes, segments of DNA, are transcribed into messenger RNA (mRNA), which is then translated into proteins that determine traits and perform various functions. The regulation of gene expression also allows cells to respond to environmental changes and differentiate into various cell types. Thus, the DNA sequence and its regulatory mechanisms shape both the physical characteristics and the operational roles of cells.
