Which of the following are properties of the phage library used by researchers to identify "Area Codes" of specific tissues? There is one correct answer.
| 
 A) Each individual phage expresses a single peptide, and the library was used by injecting all phages at the same time.  | 
| 
 B) Each individual phage expresses a single peptide, and the library was used by injecting one phage at a time.  | 
| 
 C) Each individual phage expresses many different peptides, and the library was used by injecting all phages at the same time.  | 
| 
 D) Each individual phage expresses many different peptides, and the library was used by injecting one phage at a time.  | 
B) each individual phage expresses a single peptide and library was used by injecting one phage at a time. each phage will interact and therir display will be shown. After that it is washed and another phage is inserted.
