the stages of mitosis occurring simultaneously on a meristem? Explain

Imagine a nucleus that has 10 chromosomes. How many chromosomes does it have before prophase begins? How many chromosomes does each daughter nucleus have after telophase has been completed? How many chromatids are present in the one mother nucleus before prophase begins? How many chromatids are present in each daughter nucleus after telophase has been completed? How many chromatids are present if you add together all chromatids in both daughter nuclei after telophase has been completed?

Draw a well labelled diagram to show the anaphase stage of mitosis in a plant cell having four chromosomes.

Colchicine is a poison that acts to inhibit the development of spindle fibres. Describe the effects on mitosis in a cell that has been treated with colchicine.

A scientist studying a group of somatic cells notices that when the cell cycle is complete, half of the daughter cells have no chromosomes and the other half have 92 chromosomes. In what phase of mitosis did an error most likely occur? Explain.

During anaphase of mitosis what seperates

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…

Which of the following events does not normally occur in mitosis?     Separation of sister chromatids from each other     Formation of synaptonemal complexes     Attachment of spindle fibers to centromeres     Movement of sister chromatids to opposite poles     Alignment of chromosomes along the metaphase plate

why might a cell spend longer in interphase that in any of the stages of mitosis
