Detailed explanation-1: -By housing the cell’s genome, the nucleus serves both as the repository of genetic information and as the cell’s control center. DNA replication, transcription, and RNA processing all take place within the nucleus, with only the final stage of gene expression (translation) localized to the cytoplasm.
Detailed explanation-2: -They discovered a fundamental mechanism of how proteins protect chromosomes while DNA is being copied (a process called DNA replication), which relies on a protein called RPA. Cells have a limited amount of this protein, which they use as ‘band aids’ to protect the DNA temporarily during replication.
Detailed explanation-3: -This nuclear deformation results in a breaking of the nuclear envelope, for which cells have a mechanism to reseal. This nuclear opening also results in DNA damage, and inhibiting the repair of the DNA damage leads to cell death.
