The brain is the super organ of the body , it sends signals and communicates with the other parts of the body through the central nervous system.
<u>Explanation:</u>
The brain is the organ that reacts and responds to various activities that take place in the body. The signals are in the form of chemical or electrical impulses that are sent across the organs of the body.
The activities that happen across the organ systems are communicated to the brain and the necessary measures are got from the brain through sending impulses or chemical signalling molecules.
The human mitochondrial DNA (mtDNA) is a double-stranded, circular molecule of 16 569 bp and contains 37 genes coding for two rRNAs, 22 tRNAs and 13 polypeptides. The mtDNA-encoded polypeptides are all subunits of enzyme complexes of the oxidative phosphorylation system.
