Cell Cycle Basics
This repeated pattern of growth, DNA duplication, and division occurs in eukaryotic cells.
What is the cell cycle?
This part of interphase is when DNA replication occurs.
What is S phase?
This stage is when chromosomes condense and become visible.
What is prophase?
This is programmed cell death.
What is apoptosis?
This describes the cell membrane being “picky” about what enters and leaves.
What is selectively permeable?
These are the two main purposes of the cell cycle.
What are growth and repair?
This phase is when the cell grows and makes proteins.
What is G1 phase?
Chromosomes line up in the middle of the cell during this phase.
What is metaphase?
These control points regulate when the cell cycle starts or stops.
What are checkpoints?
Transport that requires no energy and moves down a concentration gradient.
What is passive transport?
This phase of the cell cycle is responsible for cell growth.
What is interphase?
One half of a duplicated chromosome is called this.
What is a chromatid?
Sister chromatids separate and move to opposite ends in this phase.
What is anaphase?
Uncontrolled cell division is known as this disease.
What is cancer?
The diffusion of water across a membrane is called this.
What is osmosis?
By the end of interphase, the cell has this many full sets of chromosomes.
What are two full sets of chromosomes?
These identical chromatids are joined at a centromere.
What are sister chromatids?
Nuclear membranes reform during this stage.
What is telophase?
Tumors that spread to other parts of the body are described as this.
What is malignant?
This type of solution causes a cell to swell.
What is hypotonic?
This phase separates the cytoplasm and begins at the end of mitosis.
What is cytokinesis?
The ends of chromosomes that protect DNA are called this.
What are telomeres?
Put these stages of mitosis in order.
metaphase, telophase, prophase, anaphase
What is prophase → metaphase → anaphase → telophase?
Chemicals that cause cancer by mutating DNA are called this.
What are carcinogens?
This transport uses ATP to move substances against the gradient.
What is active transport?
