The Cell Cycle
Regulating the Cell Cycle
Mitosis
DNA
100
Process by which bacteria & ameobas divide.
What is binary fission?
100
The longest phase in the cell cycle, accounting for approximately 90%.
What is interphase?
100
The loss of a cell's ability to control its own growth.
What is cancer?
100
Part of eukaryotic cell division during which the cell nucleus divides.
What is mitosis?
100
The four nitrogenous bases present in DNA.
What are thymine, adenine, cytosine & guanine?
200
Sponges and hydras undergo this form of asexual reprodutcion, having areas of high mitotic division in which cells replicate rapidly.
What is a budding?
200
The three phases for the entire cell cycle (in order).
What are interphase, mitosis & cytokinesis?
200
Examples include UV rays, cigarettes, chemicals & X-rays.
What are mutagens?
200
The longest phase in mitosis in which the nucleus breaks down, chromosomes condense into X shapes and centrioles with spindle fibres appear.
What is prophase?
200
Adenine base pairs with this nitrogenous base.
What is thymine?
300
Starfish can regrow new arms via this.
What is fragmentation?
300
In this sub-stage, the cell's DNA is doubled.
What is DNA replication (sub-stage of interphase)?
300
The cell cycle will not continue if this molecule is damaged or has not replicated.
What is DNA?
300
Chromosomes get pulled apart in anaphase as these proteins structures contract and shorten.
What are spindle fibres?
300
The parent strand is also called this, as it provides the correct sequence for the daughter strand.
What is a template?
400
These have a tough outer coat and can remain dormant for years until conditions are just right for growth.
What are spores?
400
The end result produces one cell with two nuclei.
What is mitosis?
400
A difference between normal cells and cancerous cells.
What is abnormally large nuclei OR grow all over each other into a tumour (no contact inhibition)?
400
The stage in which chromosomes align at the centre of the cell.
What is metaphase?
400
Area where the chromatids of a chromosome are attached.
What is the centromere?
500
Dolly the sheep was an example of this type of cloning.
What is reproductive cloning?
500
Plant and animal cells differ in the last stage due to this.
What is plant cells form cell plates (later forming cell walls) during cytokinesis?
500
These proteins control points within the cell cycle.
What are checkpoint proteins?
500
The phase in one set of chromosomes appear at each end of the cell, two nuclear membranes reform & spindle fibres disappear.
What is telophase?
500
Separates (unzips) the two strands of DNA.
What is an enzyme?
