Lab 9 Mitosis Flashcards
1) What is the form of cell division that eukaryotic cells employ for
growth, repair or regeneration of somatic cells?
2) What is mitosis?
3) What is the purpose of mitosis?
4) Certain bacteria, cyanobacteria and many single-celled organisms
reproduce by another form of mitosis called what?
5) The cell cycle is divided into two main phases, which are?
6) What is the longest phase of the cell cycle?
7) What are the three phases that interphase is subdivided into?
8) During what interphase period are most cells arrested?
9) During what interphase period do cellular processes such as
protein synthesis and metabolic activities occur?
10) During what interphase period does DNA replication take place
which results in the copying of the genetic information?
11) What is another cellular growth phase in which the cell with its
copied genetic information is preparing for the mitotic phases?
12) What is the division of the duplicated genetic material and can be
subdivided into four phases?
13) What are the four phases of the Mitotic Phase?
14) What is the longest of the mitotic phases?
15) What phase of mitosis is when the nucleoli disappears, the
nuclear envelope fragments and begins to disappear?
16) What happens during prophase?
17) Each duplicated chromosome consists of what?
18) The two sister chromatids are held together where?
19) When do the chromosomes move to the metaphase plate and
line up single file at the center of the cell?
20) The centromeres break and the sister chromatids separate and
move toward opposite poles of the cell during what phase of the
mitotic phase?
21) What is each chromatid considered after separation?
22) As the cell continues to elongate, the nuclear envelope and
nucleoli reappear during what phase of the mitotic phase?
23) The division of the cytoplasm is called what?
24) What occurs during telophase to create two separate daughter
cells?
25) In animal cells, what develops to pinch the cell into?
26) In plants, what begins to form between the new daughter cells?
