The two libraries
Marie and her library of ancient DNA are now back upstairs. „This is the only lab, where you have a clear view of the old clock at the German National Library across the square“, she points out. After two days in the cleanroom down in the basement, I share her appreciation for green trees and a view.
Then it’s back to work.
During indexing, a short sequence of specific bases is attached to the DNA-snippets in each sample, so each snippet can later be identified and easily re-assigned to its lot. Then the samples are amplified, copied really, so they have enough material for sequencing.
This is all for this day.
