Exercise 10

You have just gotten back the results from an RNA- seq analysis of mRNAs from liver. You had anticipated counting the number of reads of each mRNA to deter- mine the relative abundance of different mRNAs. But you are puzzled because many of the mRNAs have given you results like those shown in Figure Q8-4. How is it that dif- ferent parts of an mRNA can be represented at different levels?
