Each chromosome consists of?
two identical “sister” chromatids
26
Each pair of chromatids is attached at an area called the ?
centromere
27
PMAT
▪Prophase ▪Metaphase ▪Anaphase ▪Telophase
28
the first and longest phase of mitosis
Prophase
29
The ______separate and take up positions on opposite sides of the nucleus.
centrioles
30
The centrioles lie in a region called the?
centrosome
31
helps to organize the spindle
centrosome
32
a fanlike microtubule structure that helps separate the chromosomes
Spindle
33
The phase where spindle fibers appear
PROPHASE
34
Nucleolus and nuclear membrane (envelope) disappear
PROPHASE
35
The second phase of mitosis
METAPHASE
36
The _____ line up across the center of the cell
chromosomes
37
connect the centromere of each chromosome to the poles of the spindle
Microtubules
38
Shortest Phase
METAPHASE
39
Chromosomes attach to spindle fibers in center of the cell
METAPHASE
40
The third phase of mitosis.
Anaphase
41
The sister chromatids separate into individual chromosomes.
Anaphase
42
Centromeres split apart and chromatids separate from one another. Each chromatid moves to opposite poles.
ANAPHASE
43
The fourth and final phase of mitosis.
TELOPHASE
44
Chromosomes gather at opposite ends of the cell and lose their distinct shape
TELOPHASE
45
A new nuclear envelope forms around each cluster of chromosomes
TELOPHASE
46
Chromatids unwind back into chromatin
TELOPHASE
47
Chromosomes reach opposite poles of cell
TELOPHASE
48
Nuclear envelope and nucleolus reappear reforming the nucleus
TELOPHASE
49
Spindle fibers disappear
TELOPHASE
50
New double membrane (cell membrane ) gain to form between 2 nuclei (cell pinches)
