Cell Cycle
The series of events that take place in a cell as it grows and divides.
Interphase
The phase of the cell cycle where the cell prepares for division, including growth and DNA synthesis.
Mitosis
The process of cell division that results in two identical daughter cells.
Cyclins
Proteins that regulate the cell cycle by activating Cyclin-dependent kinases (Cdks).
Cyclin-dependent kinases (Cdks)
Enzymes that, when activated by cyclins, help to regulate the progression of the cell cycle.
Checkpoints
Points in the cell cycle where the cell checks for internal and external conditions before proceeding with division.
G1 Checkpoint
A cell cycle checkpoint that assesses whether the cell is ready for DNA synthesis.
S Phase (Synthesis Phase)
The phase in the cell cycle where DNA is replicated.
Prophase
The first stage of mitosis where chromosomes condense and the mitotic spindle begins to form.
Metaphase
The stage of mitosis in which chromosomes align at the cell's equatorial plate.
Anaphase
The stage of mitosis where sister chromatids are pulled apart to opposite sides of the cell.
Telophase
The final stage of mitosis where the nuclear envelope re-forms around each set of chromosomes.
Cytokinesis
The process that divides the cytoplasm of a parental cell into two daughter cells after mitosis.
Growth Signals
'Go' signals that promote cell division, including growth factors and hormones.
Contact Inhibition
A 'Stop' signal that prevents cell division when there is insufficient space.
Differentiation
The process by which cells become specialized in structure and function.
Chromosomes
Structures made of DNA and proteins that contain genetic information.
Replication Fork
The area where the DNA double helix separates into two single strands for replication.
Leading Strand
The DNA strand that is synthesized continuously in the same direction as the replication fork.
Lagging Strand
The DNA strand that is synthesized discontinuously in short sections known as Okazaki fragments.
