The Endosymbiotic theory talks about how the ancestors of modern eukaryotic cells were once 2+ prokaryotic cells. This theory says that one prokaryotic cell basically lived inside another prokaryotic cell and these cells formed a long term relationship. The prokaryotic cell eventually became a permanent part of the host and eventually evolved into modern day eukaryotic cells.
<em>Gene Silencing is passed from age to age of isolating cells,</em> presenting a sub-atomic memory of the qualities that cells turn off as they obtain increasingly specific capacities
<em>The quality guideline is a significant piece of typical advancement. </em>
Qualities are turned here and there in various examples during advancement to make a synapse look and act not the same as a liver cell or a muscle cell, for instance
<em>Quality guideline additionally permits cells to respond rapidly to changes in their surroundings.</em>
