TQT Time

Bios,

Please submit your TQTQs for this week as a response to this post. Look ahead in your text and look at the LAC operon in bacteria and gene expression in eukaryotes for inspiration. A test looms, I just am not sure when.

Bios,

You asked for the URL to the central dogma animation so here it is - http://207.207.4.198/pub/flash/26/transmenu_s.swf

Also TQT is on the horizon.

Your Flies

Bios,

Just an update on your flies. Most of the vials look great with many larvae and pupae. I expect adults to emerge any time now. There were some vials that did not produce - oh well, we should still be able to have plenty of data. On to chi-square tests!

Get some rest as the mid-winter break comes to a close. I hope you used this time to read your text because a test looms. If I do not submit another post before then, see you Monday.

Mr. Baker

Finally, TQT - for Monday

Bios,

I have finally found the time for the TQT post. Please write your TQTs as a comment to this post.


What sex is this fly?

Considering the class content, let me take a minute to review what you should , in general terms, know by now.
1. Offspring obtain genes from their parents by inheriting chromosomes.
2. Like begets like - sort of.
3. Meiosis; know the stages and what role it plays in life cycles.
4. What meiosis has to do with the origin of genetic variation.
5. Mendel's principles and how they lead to predicting probabilities.
6. Exceptions to simple Mendelian transmission.
7. Mendelian inheritance in humans and pedigree analysis.
8. Genes and chromosomes; TH morgan and his "Fly Lab", Morgan traced a gene to the behavior of a chromosome.
9. Linked genes, how they alter Mendelian expectations, crossing over produces recombinants, and using recombinants to map genes.
10. Chromosomal errors.
That takes us through chapter 15. I am planning to test chapters 13-21 on or around February 27. Get to reading.

The Stuff of Life

I just wanted to post a book I heard about on Science Friday. It's a genetics comic book that looks like it goes into pretty good detail. If you need a visual way to study genetics for the AP exam, it might help.
