Question 7 of 7
7. Question
A heterodimer is run through a native gel and SDS-PAGE under reducing conditions. In the native gel there is a single band at the 121 kDa band mark. In the SDS-PAGE gel there are two bands one of which is at the 90 kDa mark. Given the following information the smallest subunit of the heterodimer contains approximately:
