Final answer:
During the S phase of the cell cycle, the genetic information is duplicated and checked for errors. This is important to prevent gene mutations that can lead to cancer.
Step-by-step explanation:
During the S phase of the cell cycle, the genetic information is duplicated and checked for errors. This is an important process because errors in DNA replication can lead to gene mutations, which can ultimately result in the development of cancer. If the genetic information is not properly checked, these mutations can be passed on to the daughter cells and lead to a faulty protein that plays a key role in cell reproduction.
