The answer is a hair root.
Nuclear DNA is commonly extracted from the hair root. The hair root consists of keratinocytes. Keratinocytes are cells found in the epidermis. As all other cells, they contain DNA material. When keratynocites die, they get converted into keratoid material in the process of cornification. As a consequence, d<span>ead cells do not contain DNA material. Therefore, the hair root is the best source of nuclear DNA than shed or cut hair when working with hair sample.</span>
        
                    
             
        
        
        
Answer:
If 10 glucose molecules are broken down, 320 ATP molecules will be generated during the electron transport chain.
Explanation:
In the electron transport chain, high energy electrons travel across a series of proteins embedded in the inner mitochondrial membrane, releasing energy in the process.Hydrogen is pumped from the matrix into the intermembrane space, therefore an hydrogen ion gradient is formed across the inner membrane.These proton are then pumped back into the mitochondrial membrane where the synthesis of ATP from ATP synthase takes place.
In the electron transport chain, a total of 32 ATPs are generated per glucose molecule.
so if 10 glucose molecules are broken down:
1 glucose ⇒ 32 ATPs
10 glucose ⇒ 10*32
                        320 ATP molecules
 
        
             
        
        
        
Answer:
In the lysogenic cycle, the viral genome gets incorporated into the host genome and replicates with the host genome. In the lysogenic cycle, no proteins and enzymes of the virus are formed while in the lytic cycle protein of viral capsid form and new phages generate in the host cell.
So as the viral genome integrates into the host genome in the lysogenic cycle, therefore, it is difficult for any drug to differentially act on the viral genome. So there are great chances for drugs to target the host genome in the host cell.  
But in virus that replicates through lytic cycle drugs can selectively act on viral enzyme and proteins. Therefore it is difficult to make a drug that affects lysogenic virus.
 
        
             
        
        
        
The overall function of the digestive system as digestion and absorption of food stuffs, and the general activities of each digestive system organ is; Ingest, digest, absorb, defecate. 
Ingestion involves placing food into the mouth, propulsion involves propelling food from one organ to the next using peristalsis. Mechanical digestion involves the physical fragmenting food into smaller particles. Chemical digestion refers to breaking down food molecules to building blocks by enzymes. Absorption is the transport of digested end products to blood or lymph; and finally Defecation which involves the elimination of indigestable material from GI tract by anus.
