geneticist is working with a new bacteriophage called phage Y3 that infects E. coli. He has isolated eight mutant phages that fail to produce plaques when grown on E. coli strain K. To determine whether these mutations occur at the same functional gene, he simultaneously infects E. coli K cells with paired combinations of the mutants and looks to see whether plaques are formed. He obtains the following results. (A plussign means that plaques were formed on E. coli K; a minussign means that no plaques were formed on E. coli K.)
How many cistron belong to these mutation?

Following are certain strategies used by pathogen to attack over the host plant that describe plant-pathogen interactions:
I II
A. Necrotrophic pathogens i) most of the plant tissue remains alive and only minimal cell damage can be observed, as the pathogens feed on substrates provided by their host
B. Biotrophic pathogens ii) In which the host cells are kept alive as described for biotrophic Pathogens and followed by a necrotrophic stage, in which the pathogens can cause extensive tissue damage
C. Hemibiotrophic pathogens iii) attack their host by secreting cell wall–degrading enzymes or toxins, which eventually kill the affected plant cells, leading to extensive tissue maceration. This dead tissue is then colonized by the pathogens and serves as a food source
Which of the following above combination is correct?
