Biology

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.

Maia sits down and starts to take notes, raises hand "What if they do? Have the same profile?"

"Extra credit?" Angelus grinned. "Thanks, teach. Always knew you liked me."

George cracks an eye, contemplates taking notes, decides against it, and goes back to her nap.

*Jonathan walks in and starts taking notes. He seems more interested in what led to the forensic studies than the studies themselves*

*signs in, moving better than yesterday*

Extra credit is good.

Wednesday arrives a little late, looking very much as if she'd met with some accident along the way. Her skirt is ripped and there's a long tear in the side of her backpack, which she is carrying in one hand. Wearing a look of supreme irritation, she apologizes to Professor Sidle and finds a seat in the back.

Belthazor signed in for class, but really did not want to be there. Obviously distracted, he only paid half-attention to the lecture.

*spends class wondering if/how cylon-replicated DNA is compatible with human DNA*

::After class, Cally approaches Ms. Sidle::

Ms. Sidle, I, uhhh... Just wanted to make sure you knew I was here. ::raises her bandaged hands in front of her::

I kinda can't sign the roll sheet.

Yes! Extra credit. I knew I was in the middle of that shit for a reason.

*flips open his notes and starts jotting stuff down, then he surreptiously flips open a smaller black notebook and writes in that occasionally*

[swerval_zero]

Extra credit? Wicked swerval!

*takes notes, as this is fascinating stuff*

*scribbles double helix: discovered over pints in the margins of her notes*

*comes in, places a coffee down on Saras desk then takes his seat, quite a bit late*

*is still grinning like a maniac*

*Lilly walks into class and sits down. She acts like she's taking notes, but it's really a list of plans for homecoming.*

[fates_jaye]

*is totally here, and on time and everything*
