Alertness is regulated by a group of nuclei (bodies of nerve cells) spread throughout the brain stem and the medulla called the reticular formation.
These nuclei are a relay system that connects the lower parts of the nervous system to the cerebral cortex and integrates signals and information in the brain.
Answer:
DNA Sequencing.
Explanation:
In field of Biotechnology, we use an instrument known as "Gel Electrophoresis" in this instrument, different sized DNA Fragments are placed. After that, Electricity is applied due to which Negatively charged DNA fragments move towards positive charge through Gel Medium. Small sized DNA Fragments reach destiny before large fragments.
This is an application of Electrophoresis.
