A team of researchers has uncovered a previously unrecognized role of mitochondrial protein synthesis in the maintenance of intracellular iron distribution. Disruption of this process was found to ...

This process of protein synthesis occurs in two stages - transcription and translation. When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA).

So how does protein synthesis make hair? If you've looked at the activity (or even the text version of the activity), you know how a section of DNA instructs a cell how to make a protein.
