used to infect the bacterial cell. Sometime after infection, the radioactivity was measured outside in the ghosts of phage and inside of bacterial cell to see whichcomponent of the phage entered the bacterial cell. You are asked to do a similar experiment and you aregiven radioactive isotopes of P, S, C, N and H. Which of the following is expected to happen? [P=phosphorous ; S =sulfuri C=c arlon ; N=nilro gen ; H=hydrogen] tKs,Ae zu'fs,6n tn+lo b"#h b'orh P and N will be seen inside the bacteria whereas S, C and H will be seen outside the bacteria. S andC will be seen inside the bacteria whereas P, N, and H will be seen outside the bacteria. P will be seen only inside of the bacteria S, C, N, and H are seen both inside and outside the bacteria. P will be seen only inside the bacteria, S will be seen only outside the bacteria and C, N, and H will be seen both inside and outside bacteria. e.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
