Answer:
3. Separation of sister chromatids
Explanation:
Before entering mitosis or meiosis, DNA contained in a cell duplicates and  and each chromosome will have two sister chromatids.
-  In mitosis the sister chromatids separate to produce two daughter cells that have the same information as the original cell before the DNA duplicated.
- On the other hand, meiosis consists of two cell divisions. During meiosis I, homologous chromosomes separate, producing two daughter cells that have half the information the original cell had, but each chromosome still has two sister chromatids. During meiosis II, the sister chromatids separate, and each daughter cell produces two more daughter cells, that now have a single homologous chromosome of the pair, and which has a single chromatid.
 
        
             
        
        
        
The ATP molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. In this form, energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.
