Interphase & Cytokinesis
A cell spends the most amount of time in this phase of the cell cycle.
Interphase
What does the nuclear membrane begin to do at the beginning of Prophase, and finishes completely during Metaphase?
Dissolves
During Anaphase, chromosomes split at the _______
Centromere
Cancer occurs when cells _______ uncontrollably
When a stem cell has converted into a mature cell with a purpose, this is called its ________
Specialization
2
Each chromosome is made up of two identical copies of ______
DNA
During Telophase, when the daughter chromosomes uncoil, they are referred to as _________
Chromatin
A cancerous lump of cells is referred to as a _________
Tumour
Even when comparing cells with different specializations, they will still have the same _____
DNA
In plant cells, during cytokinesis, a new cell is created when _______ forms.
Cell plate
Duplicated DNA condenses into this short and thick structure:
Chromosome
During Anaphase, where do the daughter chromosomes get pulled by the spindle fibres?
Opposite poles of the cell
UV light, chemicals, and radiation are called considered __________
Carcinogenic
The process where an unspecialized stem cell is turning into a specialized cell
Differentiation
During Interphase, DNA exists as a long, thin strand called ______
Chromatin
During Metaphase, where do chromosomes line up?
The middle of the cell
Before they are pulled apart, each strand of a chromosome is called a ________, and then after they are pulled apart they are called _________
Sister chromatid, daughter chromosomes
The alteration in regular DNA that leads to cancer is called _________
This type of stem cell is limited in what it can differentiate into, depending on where it is found in the body:
Adult stem cell
In preparation for division, what does DNA do during this phase?
Duplicate
During Metaphase, the mitotic spindle attaches to this part of the chromosome:
Centromere
_________ begins to form around the daughter chromosomes once they reach their new poles in the cell during Telophase
Nuclear membranes
___________ control the cell cycle and determine when a cell starts and stops dividing
Chemical signals
This type of stem cell is very potent and is often easy to obtain:
Embryonic stem cells
