18
Q

Individual spindle fibers bind to a kinetochore structure on each side of the centromere. The chromosomes continue to condense.

A

prometaphase

19
Q

The chromosomes align themselves along the metaphase plate of the spindle apparatus

A

Metaphase

20
Q

The shortest stage of mitosis, the centromeres divide, and the sister Chromatids are pulled apart or disjoined all move to the opposite ends of the cell

A

Anaphase

21
Q

What do you call to the separated sister chromatids

A

Daughter Chromosomes

22
Q

It is the stage where the nuclear him brave reforms around the chromosomes grouped at either poll of the cell.

A

Telophase

23
Q

It is a process when the chromosomes uncoil and become diffuse, and the spindle fibers disappears

A

Telophase

24
Q

It’s a process in plants a cell plate forms along the live of the metaphase.

A

Cytokinetic

25
Q

The final cellular division to form new cells

A

Cytokinesis

26
Q

It ensures that the two new cells (daughter cells) resulting from a cell undergoing mitosis each have precisely equal amounts of DNA

A

Mitosis

27
Q

the daughter cells have the save number of Chronosones and distribution of DNA as the parent cell

A

Mitosis

28
Q

initiated with the appearance of a ringlike preprophase band of microtubules just beneath the plasma membrane

A

Mitosis

29
Q

the chromosomes become shorter and thicker, and their two-stranded nature becomes apparent

A

Prophase

30
Q

the nuclear envelope dissociates, and the nucleolus disintegrates.

A

Prophase

31
Q

What is the first sequence of Prophase?

a) marked by the appearance of the chromosomes as faint threads in the nucleus.

b) The coils appear to tighten and condense until the chromosomes have become relatively short, thick, and rodlike, with areas called CENTROMERES holding each pair of chromatids together.

c) Spindle fibers consisting of microtubules have developed

d)chromosomes gradually coil or fold into thicker and shorter structures, and soon, two strands, or CHROMATIDS, can be distinguished for each chromosome.

e) prophase progresses, the nucleolus gradually becomes less distinct and eventually disintegrates.

f)spindle fibers extend in arcs between two invisible poles located toward the ends of the cell.

37
Q

the main feature is the alignment of the chromosomes in a circle midway between the two poles around the circumference of the spindle and in the same plane as that previously occupied by the preprophase band.

A

Metaphase

38
Q

involves the sister chromatids of each chromosome separating and moving to opposite poles.

A

Anaphase

39
Q

What are the five main features of telophase?

A
  • each group of daughter chromosomes becomes surrounded by a reformed nuclear envelope
