It is because of different arrangements of nucleotide bases.
<h2>Explanation</h2>
There are only five types of nucleotide basis are present in the genetic material which makes up the all the genetic information of the individuals. These nucleotides are named as Adenine, Thymine, Guanine, Cytosine and Uracil. In all the living beings on the earth, these only five nucleotides are present which decides their behaviour and functions on the earth. These five bases have features to get any arrangements according to the situation. Their different arrangement at the heredity material makes the difference in all living beings regarding their behaviour.
That execution outside of the cell in which it is produced
is Enzymes it degrade large molecules into units that are little enough to be
pass through across the cell membrane and into the cell where they can be very
useful.
