What is an example of central dogma?

An example of the central dogma of molecular Biology is the process of gene expression, where DNA is transcribed into messenger RNA (mRNA), which is then translated into a protein. For instance, the gene for insulin in humans is transcribed into mRNA in the nucleus, and this mRNA is transported to the ribosomes in the cytoplasm, where it is translated into the insulin protein. This sequence illustrates the flow of genetic information from DNA to RNA to protein, a fundamental concept in biology.
