Answer:
Explanation:
The eukaryotic genes of interest can be expressed in the prokaryotic genome or plasmid vector. The following are the steps used for the purpose of expression of eukaryotic genes in the prokaryotic genome.
1. Amplification of the target gene of interest from the eukaryotic genome by PCR or polymerase chain reaction.
2. The selection of the plasmid and digestion of the plasmid DNA with the restriction enzyme.
3. Ligation of the amplified DNA fragment and the plasmid.
4. Introduction of the ligated plasmid into the prokaryotic host organism.
Belonging to the large family of alcohols, propylene glycol is a chemical element widely used by the food industry thanks to its recognized emulsifying properties. It is referable to its acronym E1520. This colorless, low volatile and soluble diol is also used in many other industries. Pharmaceutical, cosmetic, aeronautic, textile industries ... Propylene glycol is involved in the composition of many polymers such as polyester. Non-toxic when inhaled, propylene glycol is used in electronic cigarette filling fluid to produce an aerosol effect comparable to that of smoke.
With respect to polypropylene glycol, each condensation of propylene glycol causes a loss of a water molecule
C3H8O2 + C3H8O2 + C3H8O2 ==> C9H20O4 + 2H2O
Short-term memory holds information for 15 to 25 seconds and stores it according to its meaning rather than just as mere stimulation. However, it is not really true that short-term memory can be retained only for this short amount of time. It has been shown in different studies that it can be held even longer.
