Who is the real Anastasia?

SAM_0118Biotechnology students at Stratford STEM Magnet High are trying to figure out who is the real Anastasia.  The teacher set the scenario based on the actual case study of the Russian Romanovs from the early 1900’s.  The students used simulated DNA from 4 possible Anastasia’s (their daughter) and determined if any could possibly be the real Anastasia. This was done through DNA fingerprinting with gel electrophoresis. Just like real Crime Scene Investigators, students went to work to solve the case.


The biotechnology students have been studying DNA fingerprinting through gel electrophoresis.  In gel electrophoresis, an electrical current is applied to a gel matrix which contains samples of DNA, RNA, and protein. The electric current causes the protein or nucleic acid molecules to move through the gel, allowing for the separation of molecules of different sizes. This technique is used to detect or isolate molecules of a particular size from a mixture of nucleic acids or protein organisms.

Wow!  Case solved thanks to the smart students at Stratford STEM Magnet High.
