I wonder why we just remove adapter from 3' end of reads and not both sides? For example when using Illumina TruSeqâ„¢ Small RNA, they use RA5 and RA3 adapter, so why we just trim 3'?

For small RNA, do you trim for quality from both sides of a read if both sides does not have good quality?

Thanks Sara

Take a look at the figure at the bottom of this page: Unless your inserts are shorter then the length of sequencing you should never see adapters except on the 3'end.
