Simply put, the central dogma states that genetic information starts out as strands of DNA in the cell’s nucleus, is first copied (transcribed) into complementary ribonucleic acid (RNA), and is then transported to the cell’s ribosomes to be translated into the amino acids that are used in protein formation and function.
This process continuously occurs for the approximately 19,000–20,000 protein-coding genes found in the human body. Through this process of gene expression, the information stored in the genes becomes actively useful for the organism."
