¿Qué es el ciclo celular?
¿Qué es el ciclo celular?
The cell cycle refers to the sequence of events occurring throughout a typical cell’s life. In eukaryotic cells, the somatic cell cycle has two ...
Interfase
Interfase
The cell cycle occurs over approximately 24 hours (in a typical human cell) and in two distinct stages: interphase, which includes three phases of the ...
El sistema de control del ciclo celular
El sistema de control del ciclo celular
The cell cycle is an organized set of events that leads the cell to divide into two daughter cells, each containing chromosomes identical to the parent ...
Moléculas reguladoras positivas
Moléculas reguladoras positivas
Mitotic cell division results in daughter cells that exactly resemble the parent cell. However, errors in the DNA replication or distribution of genetic ...
Inhibición de la actividad de CDK
Inhibición de la actividad de CDK
The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be ...
S-Cdk inicia la replicación del ADN
S-Cdk inicia la replicación del ADN
The cell cycle is a series of events leading to DNA duplication followed by the division of cell content to form two daughter cells. The cell cycle ...
M-Cdk impulsa la transición a la mitosis
M-Cdk impulsa la transición a la mitosis
Checkpoints throughout the cell cycle serve as safeguards and gatekeepers, allowing the cell cycle to progress in favorable conditions and slow or halt it ...
Los mitógenos y el ciclo celular
Los mitógenos y el ciclo celular
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell ...
Senescencia de células replicativas
Senescencia de células replicativas
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while ...
Proliferación anormal
Proliferación anormal
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. ...
Las células coordinan el crecimiento y la proliferación
Las células coordinan el crecimiento y la proliferación
Cell size is a significant factor impacting cellular design, function, and fitness. There exists some internal coordination by which cells double their ...
