Learn about the roles that DNA and genetics play in this process.
Cells are basic units of biological life.
The DNA instructions contained in each living cell design, build, and guide the processes of life through the system of protein synthesis. Ribosomes inside the cell make the necessary proteins for the cell to live. Before the ribosome can make a protein, it first needs the appropriate DNA instructions. This is called Transcription. RNA is just like DNA except that it uses ribose sugar instead of deoxyribose sugar as its backbone.
