Question

Arrange the stages of mitosis shown in the diagrams in sequential order. Use the ABCDE labels on the drawings to indicate the order.
A) a - b - c -d - e

B) c - d - e - b - a

C) b - c - d - a -e

D) b - e - c - a -d

Answer 1

Answer:

The correct answer would be B) c - d - e - b - a  

Mitosis refers to cell division in which a parent cell divides to form two daughter cells.

The process is mainly divided into four stages:

• Prophase: It can further be divided into two sub-stages; early prophase and late prophase. In the early prophase, chromosome start condensing, mitotic spindle begins to form and nucleolus begins disintegrating. Stage C represents the early prophase.
• In late prophase or prometaphase, nuclear membrane disintegrates, chromosomes finish condensing, and spindle grows to capture chromosomes. Stage D represents the late prophase.
• Metaphase: Chromosomes are aligned at the center of the dividing cell forming a metaphase plate. The kinetochores of the chromosome are attached with microtubules coming from opposite poles. Stage E appears as metaphase.
• Anaphase: The sister chromatids of each chromosome are separated and pull apart towards opposite poles. The sister chromatid appears as V-shaped due to pulling. Stage B appears as anaphase.
• Telophase: It is the last stage of the mitosis during which two new nuclei are formed around each set of chromosomes. Nuclear membranes reform and chromosome de-condense. Stage A appears as telophase.
