Phases
What occurs during prophase?
The DNA coils into chromosomes, the nucleus dissolves, and the spindle appear
What are chromosomes?
pairs of identical DNA
What is interphase like?
Interphase is like a resting period.
What occurs during cytokinesis?
the cell finally divides
What structure guides the movement of chromosomes?
spindle fibers
What occurs during metaphase?
The chromosomes line up in the middle of the cell.
What are chromatids?
two exact copies of DNA that make up each chromosome
Why is interphase considered the longest stage of the cell cycle?
It is preparing for division.
What happens during cytokinesis in the animal cells?
The membrane pinches and pulls apart
What is the final phase of mitosis?
Telophase
What occurs during anaphase?
Sister chromatids separate and move to opposite ends of the cell.
What is a centromere?
the point that two cromatids are connected at
Are chromosomes visible during interphase?
No, the chromosomes are not visible.
What occurs during cytokinesis in plant cells?
a cell plate is formed
What is the purpose of cytokinesis?
To separate the cytoplasm and cell membrane
What occurs during telophase?
The chromosomes uncoil, the nucleus reappears, and the spindle fibers vanish.
What are diploid cells?
when a cell contains two sets of chromosomes; body cells
Does a cell spend most of its life in interphase,
Yes, cells have to go through interphase before the process of mitosis can begin.
What is the final result of cytokinesis?
2 identical daughter cells
Which of the following does NOT occur during mitosis?
a) chromosomes condense
b) separation of the sister chromatids
c) replication of the DNA
d) formation of the spindle fibers
c) replication of DNA
What are the processes before and after mitosis?
Interphase and Cytokinesis
What are haploid cells?
when a cell contains one set of chromosomes; gamete
What occurs during interphase?
the cell is growing and performing its normal cell duties
Is cytokinesis at the start or end of mitosis?
At the end
What is the cell cycle?
it is the entire series of events cells go through when they divide
