Brdu birthdating protocol Brunei local porn

Since the two chemicals are analogous, some spots of the genetic code that call for Thymidine will instead receive Brd U.

The special thing about Brd U is that it can be stained with an antibody using immunohistochemical methods, whereas Tritiated Thymidine is only detected by radiographic techniques.

When a scientist injects Brd U into the bloodstream of a test animal, the chemical becomes available to all cells – most importantly, those which are proliferating.

As the cells build their new genetic strand, they pull either Thymidine nucleotides or Brd U analogues from their environment.

These microorganisms will then incorporate Brd U into their DNA as they grow.
