Caption A cartoon schematic of cell-free protein synthesis, a biotechnology that harnesses the cell's genetic code into a test tube. The schematic represents a simplified approach that allows ...

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.

HHMI scientists and their colleagues discover a new mechanism of protein synthesis. Ribosomes are the cell’s molecular machines, responsible for translating genetic information in messenger RNA into ...

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).
