Good day, everyone. *glancing out over the class* For those of you who managed to avoid the zombies, good job. And those of you who actively fought the zombies now have extra credit. Decomp formula is in the back if needed.

Today we will begin talking about DNA in the forensic sense.

Any type of organism can be identified by examination of DNA sequences unique to that species. Identifying individuals within a species is less precise at this time, although when DNA sequencing technologies progress farther, direct comparison of very large DNA segments, and possibly even whole genomes, will become feasible and practical and will allow precise individual identification.

To identify individuals, forensic scientists scan 13 DNA regions that vary from person to person and use the data to create a DNA profile of that individual (sometimes called a DNA fingerprint). There is an extremely small chance that another person has the same DNA profile for a particular set of regions.

I went in today to drop his class - and he gave me a "D" and told me I had to report to detention this Saturday. I've *never* had detention! And with all the crazy stuff at this school... I'm actually kind of scared.

Maia's mouth dropped. "They gave you detention because you dropped the class. Who? What teach-" Maia stops short as Ms. Sidle turns around. Maia puts her head down writing again watching Sara, when she turns back to the board Maia turns back to Lana "What teacher did that?"

"You should go see the principal. That is crap he gave you detention. Connor can overturn it."

Honestly, I think she scares me even more than detention!
