The answer is ‘suspect iii has 900 bp and 260 bp sized DNA fragments’
Forensic science utilizes particular sequences of DNA that are unique to people and are cut differently by restriction enzymes. These  techniques are referred to as Restriction Fragment Length Polymorphism (RFLP) and the Short Tandem Repeat (STR) Analysis. In this case, there is an exact match on the crime sample and that of the suspect.
 
        
                    
             
        
        
        
Explanation:
Cancer occurs in dividing cells only because genetic materials divide into two equal portions during division. This process may be interrupted by carcinogenes or mutagenes to make mutate cells and then render them as cancer cells. In the brain, the cells are differentiated and there is no chance to start division, then how can cancer be found in the brain.
 
        
             
        
        
        
Answer:
Most scientists believed that heredity material blended together in offspring, however, Mendel did not. he believed that an organism inherits one gene from each parent and that some alleles are dominant over others. This would mean that they would show up in the phenotype of an organism.
