The Podcast Explain is for everyone interested in DNA/RNA sequencing or technology in general. As Iuliia doesn't have a solid background in sequencing, she keeps asking "simple" - even silly at times - questions and Daniel gives his best to make us understand.

PS: I do not know how in the Parse approach the cells are treated to let the ligase and DNA enter each cell, but do not let RNA flow out of the cell at the same time. -DR -

CORRECTION: On the Illumina 1-channel chemistry, one base signal gets added, one removed at the enzymatic step: so that's one signal that stays, one that disappears, one that comes to shine and one that never shines. - DR
