Where on the transparency does cloning occur?

Cloning is a process that produces organisms that are genetically identical to a donor organism (just like identical twins are genetically identical).  Basically, you take an unfertilized egg from a female of the species you are interested in cloning.  Then you take a somatic (body) cell from the organism you wish to clone.  You remove the nucleus from each of the cells.  Then you place the nucleus of your "to be cloned" animal inside the egg.  You then replace the egg in the surrogate mom and allow it to go through normal gestation (pregnancy).  The baby will be the clone of whatever animal you were trying to make. 

 Since we cannot see the transparency you are talking about, I can only give you a generalized answer.  In the first link, you will find a diagram of sheep cloning. The actual cloning is taking place at the stage where the cell and enucleated (without a nucleus) egg are being fused with electricity.

Again, not being able to see the transparency you are referring to, I can only assume what you are asking.  I know that when we discuss cell division, like binary fission, it is often compared to cloning.  For instance, when bacteria divide after exchanging genetic information (transformation) it is like cloning, because now you have two identically genetic organisms.  When we discuss the lysogenic cycle of virus replication, you could compare cloning to the division of the infected host cell during the inactive phase of the cycle.  Also, any type of asexual reproduction (binary fission, vegetative propogation, budding..etc) could technically be considered cloning.  Usually the term "cloning" is used to refer to the human manipulation of an organism to create a clone, as in the situation of Carbon Copy "CC" the cat or Dolly the sheep.
