2a,b). Next, we transfected cells with wild-type and mutant eGFP-AR-V7 variants, which are localized in the nucleus, and measured cluster formation (Fig. 2c). We observed a decrease of the spatial variance of fluorescence intensity, that is granularity, in cells expressing the 8YtoS, 14...
A and B marks are not given for fortuitously “correct” answers or results obtained from incorrect working. • Note: B2 or A2 means that the candidate can earn 2 or 0. B2/1/0 means that the candidate can earn anything from 0 to 2. The marks indicated in the scheme may not be ...
