There is on answer
what is cyclin-dependent kinase (CDK)?
uncontrolled cell growth and division. It is basically related to the abnormal functioning of cell cycle regulators
an enzyme that controls the cell cycle and is activated by cyclin
achieved by a group of proteins, called cyclins, and enzymes, known as cyclin-dependent kinases.
enter the blood vessels which may carry them to different parts of the body. In this way, cancer will be spread throughout the body.
what is Stem cells?
are undifferentiated cells that can develop into any type of specialized cells when suitable conditions are available. Her is pic in alef
Types of Stem Cells There are two types of stem cells
programmed-cell death is a process that occurs when specific factors activate self-destructive enzymes in the cell, causing its death.
For a cell cycle to proceed successfully, there are different checkpoints throughout that cycle to monitor for errors.
