Mitosis: Telophase 

Telophase is the final stage. The chromatids will be pulled to opposite poles and refrom back into chromatin.  The two newly formed nulcei will than be separted by cytokinisis. 
                       final stage      k 

Read the pages indicated by G-6, examine behavioral objective 9 and focus on the steps involved during telophase. 
 

Telophase - This stage is the opposite of prophase. When the chromosomes reach the poles the following events occur: 

1. Nuclear membrane and nucleoli reform. 
2.Chromosomes uncoil and untwist to reform chromatin. 
3. Spindles break down and disappear. 
4. Centrioles remain next to the nucleus. 
 
Write these in your notes.

26. Examine the figure above. How many chromosomes are present in EACH of these two cells? 

      a) 2                          b) 3                             c) 6                                d) 12

27. The chromosomes at this stage consist of two sister chromatids held together by a centromere. 

               a) true                                                                        b) false

 Using the figure above (Answer Check) draw in your notes, the  three pair of chromosomes with the genes "A" and "B" on the long red and blue homologous pair as they would appear during telophase.
