The ability of cells to communicate, that is, receiving and sending signals from and to other cells, determines the interaction between unicellular organisms and regulates the function and development of the body of multicellular organisms. For example, bacteria communicate with each other in the quorum sensing process to determine whether they are sufficient before forming biofilms, while cells in animal embryos communicate to coordinate the process of differentiation into various cell types.

The method used here is agarose gel elecrtrophoresis in which DNA ladder is used which is a set of standard used to determine the size of DNA used .The DNA ladder is put adjacent to the DNA fragments to be visualized Suppose if the ladder shows 300 basepair so the DNA adjacent to this number will be of this size.These are the set standards used to determine the size of DNA or RNA. For a range we can take 2% of agrarose to run DNA fragments upto 500 Basepair. Most of the amplified DNA falls into this category size.
