Ribonucleotide reductase

Ribonucleotide reductase is an essential enzyme in our cells that converts RNA building blocks (ribonucleotides) into DNA building blocks (deoxyribonucleotides). This process is crucial for DNA replication and repair, allowing cells to divide and maintain their genetic information. The enzyme acts as a molecular switch, selectively reducing specific molecules to produce the correct components needed for DNA synthesis. Its precise regulation ensures that cells make the right amount of DNA precursors, maintaining genetic stability and supporting growth and recovery in all living organisms.
