    well i wrote that group C was used as a marker to trace if vector was reaching the desired location and where it was going
    also D was there to compare the aftereffects and to what extent the mice went back to normal and to compare
    and the virus was disabled to replicate becuz it can randomly insert gene anywhere so couldve led to cancer and also has side effects.
    and well the therapy was beneficial with the correct dose overall but they were mice and ppl might respond differently so cannot say

    oh well i guess v cant say with such a small number of students
    overall i guess it wasnt too hard but not too easy at the same time
    i think the thresholds going to be in 60s

    RuBP and Rubisco are located in the bundle sheath cells and PEP Carboxylase is found in the mesophyll cells.
