<span>The bacteria make proteins from the inserted modified genes.</span>
Ftsz, mreb, and cres ,proteins regulate the shape and structure of bacterial prokaryotic cells. These proteins are homologous to the Cytoskeleton in eukaryotes. Homologous meaning they have the same evolutionary origin but not necessarily having the same function. Cytoskeleton forms a framework for the movement of organelles around the cytoplasm, most organelles are attached to the cytoskeleton.
The reasons are:
- the blood is very low on nutrition
- the leech is not feeding itself regularly
The leech slows it metabolism a lot, so it can survive on very low nutrition. The blood is very low on nutrition, and it is the leech's food source, so the evolution made it preserve energy.
The leach doesn't have the opportunity to feed itself on regular basis, so it takes maximum advantage of any opportunity and consumes as much blood as possible so that it can survive long term when it will not have food at disposal.
