Flashcards
Cell Cycle Checkpoint
Cell Cycle Checkpoint
A built-in control mechanism that checks for errors in the cell cycle before the cell moves to the next stage.
Apoptosis
Apoptosis
Programmed cell death, a natural process of cellular self-destruction to eliminate damaged or unwanted cells.
Stem Cells
Stem Cells
Cells that can divide and differentiate into specialized cells of various types, such as blood cells or skin cells.
