Metaphase and Anaphase questions




Wednesday January 23rd
During Mitosis what do you think would be the result if Metaphase was skipped and the cell went straight into Anaphase
  The chromosomes would not separate equally and each of the resulting Nuclei would have different DNA.
I look under a microscope and notice a group of cells. Some cells have a nucleus that looks very “messy” with no defined structures.  There is one cell though that has very distinct structures forming within the nucleus.  What are these structures, what is so important about them being visible now, what stage of mitosis could we infer it is in?

 The Structures are Chromosomes, what is 

important about them being visible now is that 

they have condensed (this marks the beginning of

 mitosis) therefore this would be a cell in 

prophase

What about the “messy” cells – what stage of

 the cell cycle are they in?

 The other cells around would be in interphase. 

 At this time the DNA is uncoiled and looks just 

like a "blob".
