Title: Mitosis?
Post by: Wabba Fig! on April 07, 2013, 03:16:04 pm
Would you say that this is Anaphase?

Also what stage do you guys reckon this is?
I am kinda leaning towards Early Telophase  :-\

most definitely. the pics on the exam should be clearer though, so I wouldnt worry too much. But yeah definitely anaphase, but very close to commencing telophase, but not quite there yet. (chromosomes havent yet uncoiled into chromatin, so not telophase)
this is for the first picture

This is anaphase - after the spindle fibres along the equator of the cell contract, the chromosomes split at the centromere and move to oposite sides of the cell, as can be seen in the image of that occuring.

SAC 3 in Unit 4 is on Mitosis and/or Meiosis
