Answer:
The correct answer will be option-thick bundles of fibers that allow communication between the brain’s hemispheres. 
Explanation:
Cerebral commissures are the thick fiber tract composed of white matter which connects the same cortical areas of the left and right hemispheres of the brain.
Commissural fibers include many types of fibers in which corpus callosum fibers are one of the types of fibers which act as the main Cerebral commissures.
Since these fibers connect the two hemispheres, therefore, they help in the communication between two hemispheres.
Thus, the selected option is the correct answer.
 
        
             
        
        
        
Answer:
 by the nitrocellulose membrane filter method. (more info below) 
Explanation:
Genetic relationship between mycoplasma as determined by nucleic acid homology.  DNA from each of the mycoplasma isolates tested was reacted separately by complementary RNA synthesized with homologous or heterologous DNA as a primer. The amount of DNA-RNA hybrids formed was tested using the method of the nitrocellulose membrane filter.
hope this helped!
