In the figure below are shown a pair of Southern blot gels that represent the results of a hypotheticat experiment simlar to Tonegawa's experiment in which. radionctively labelled mRNA probes were used to label restriction enzyme-treated DNA. In this typothetical experiment the mRNA probes correspond to either the V region or the C region of the andibody gene. The gal on the left thows the results using germine DNA from a lymphocyte stem cell and the gel on the ilght shows the results uging a B-cell tumor cell line (myoloma) that produces antibodios Question - Why does the gel on the right have 2 bands that are not present on the gel on the left? Provide your selection AND justify to explain Wrf your answer is cortect a) DRRA splsing occurred b) ViDJ recombination occurred on one chromosome c) V(D)J recombination occurred on both chromosomes d) Switch recombination occurred
