QUESTION 2
In order to compare transcript A and B expression levels in the same libarary based on their read/fragment counts,
which of the following factors must be considered:
O 1. The number of fragments belong to each gene in the library
02 All of the above.
3. Total number of fragments in the library (aka, sequencing depth)
O4 Length of transcripts
QUESTION 3
Which of the following quantification methods is the best way for comparison between
samples?
O 1. raw read count
2. RPKM
O 3. FPKM
O 4. TPM
QUESTION 4
What's the best way to deal with the reads/fragments which are mapped to multiple
transcripts or genome locations?
O 1. discard this read/fragment
O 2. evenly distribute this read/fragment to all the possible locations/transcripts
O 3. randomly assign this read/fragment to one of the possible location/transcript
4. Using Expectation-Maximization method to estimate the probability of the fragments to be mapped in each possible
location/transcript
