Students have asked these similar questions
With regard to the process of mitosis, which of the following pairs is NOT matched correctly?
a. Interphase - the cell grows, chromosomes replicate, and proteins are produced to prepare the
cell to divide
Ob. Prophase - chromosomes condense, and the nuclear membrane dissociates/breaks down
c. Metaphase - chromosomes move toward opposite poles (or sides) of the cell
d. Anaphase - sister chromatids separate
e. Telophase - two distinct nuclei are formed; this is the stage immediately before cytokinesis
O O O
1) What phase of mitosis is this?
Answer:
2) What is the indicated structure 1? select one.
a. chromosome
b. chromosome with two sister chromatids
c. centrioles/centrosome
d. spindle fibres
e. metaphase plate
3)If the diploid (2n) number of this cell is 8 how many chromosomes are present?
4) If the diploid (2n) number of this cell is 8 how many sister chromatids are present?
5) If the diploid (2n) number of this cell is 8 how many homologous pairs are present?
Match the stage of mitosis with the correct description.
a.Microtubles that are attached to each chromosome shorten, pulling the sister chromatids apart.
b.The chromosomes line up single file in the middle of the cell. Sister chromatids are clearly visible in this stage.
c.The chromosomes that were pulled apart reach therir respective poles. The chromosomes decondense. The nuclear envelope re-forms. The cytoplasm with organelles divides.
d.Chromosomes have replicated and appear as an "X". The nuclear envelope begins to break down. The chromosomes begin to condense into individual structures.
e.Centrosomes move to the opposite ends of the cell and establish two spindle poles.The nuclear envelope is completely degraded by the end of this stage. The chromosomes are completely consensed by the end of this stage.
f.Not actually part of mitosis; this stage is the part of the cell cycle that is not the mitotic phase. DNA is decondensed and appears diffuse throughout the…
