<span>Every living organism begins life as a single cell. Unicellular organisms may stay as one cell but they grow too. Multicellular organisms add more and more cells to form more tissues and organs as they grow. </span>

Prion which is a protein that replicates or bacteria
The p53 protein is known as the guardian of the genome because this protein prevents errors during DNA replication. It is a tumor suppressor gene.
<h3>Tumor suppressor genes </h3>
Tumor suppressor genes are genes that play fundamental cellular roles and prevent cell uncontrolled growth.
A tumor suppressor gene can repair errors that occurred during DNA replication, slow down the cycle of cell division, trigger programmed cell death, etc.
The p53 acts to control cell division and cell death, thereby avoiding the emergence of cancer cells.
