Interphase
Mitosis
Cytokinesis
Meiosis
Chromosomes and Chromosome Numbers
100
In this stage, D.N.A is copied or synthesized
What is the S phase?
100
In this stage, Kinectochore fibers move chromosomes to the middle of the cell and are held there by a kinectochore fiber
What is metaphase?
100
This is the name given to the area of the cell that when dividing, the cell membrane pinches together
What is the cleavage furrow?
100
In this stage, D.N.A coils into chromosomes and proceeds with synapsis
What is prophase 1?
100
D.N.A. wraps around this protein to make chromosomes
What are histones?
200
In the stage, the cell has grown and is now prepared for cell division. D.N.A is also proof read and repaired
What is the G2 Phase?
200
In this stage, chromosomes uncoil back to chromatin and a nuclear envelope forms around the chromosomes. The spindle fibers will also begin to disapeer
What is telophase?
200
The cleavage furrow is completed in cytokinesis, but actually begins to form in what stage of mitosis?
What is telophase?
200

In this stage, chromatids separate to opposite poles of the dividing cell

What is anaphase 2?
200
These chromosomes are all the other chromosomes that do not determine a organism'a gender
what are autosomes?
300
In this stage, the cell grows to mature size
what is the G1 phase?
300
In this stage, chromatids separate and are dragged towards opposite poles of the dividing cell
What is Anaphase?
300
In plant cells, vesicles from this organelle join together at the mid-line of the dividing cell to form a cell plate
What is the golgi apparatus?
300
In this stage, the nuclear membrane reforms around the separated chromosomes. The cytoplasm divides and 4 daughter cells are formed
What is telophase 2/cytokinesis 2?
300
If a organism's chromosome number is 122, what would be the number of homologous pairs?
What is 61?
400
This stage is when cells do not divide nor prepare to divide
What is the G0 phase?
400
In this stage, D.N.A. is shortened and tightly coiled into chromosomes and spindle fibers radiate from the centrosomes
What is prophase?
400
During cytokinesis, plant cells don't need a cleavage furrow to divide. instead they turn the cell plate into this organelle
What is the cell wall?
400
In this phase, Chromosomes line up along the equator of the dividing cell, not in homologous pairs
What is metaphase 2?
400
If a organisms number of chromosomes in a haploid cell is 97, what is the organism's chromosome number?
What is 194?
500
True or false? During the G2 phase, D.N.A. can be seen in the nucleus without staining the cell
What is false?
500
These spindle fibers connect the centrosome of a chromosome rather than opposite poles of a cell
What are Kinectochore fibers?
500

True or false? The offspring cells are exactly the same as the original cell including the same amount of chromosomes, but have half the cytoplasm and organelles

What is true?

500
In this process, portions of chromatids break off and attach to adjacent chromatids on the homologous chromosome
What is crossing-over?
500
True or false? An organism has more complex genes if the chromosome number is higher
What is false?
