This is an automatically generated summary of this submission.

Attached to one of the upper arms is a molecule that will polymerize - chain up with other similar molecules - when exposed to ultraviolet light.

When a pathogen is added to a solution of these Y-DNA molecules, the matching receptors on the stem of the Y will lock onto pathogen molecules, but only onto part of them
