GENE INDICES (this activity is also available on Mrs. LaBruyère’s website at: http://biotexan.livejournal.com )
Go to: http://compbio.dfci.harvard.edu/tgi/
Click on “gene indices”
Choose “human”
Under “sequence reports”, click on “Libraries”
Now you can make your search by using a keyword for a tissue or an organ of the human body that you wish to find a gene for.
Type a tissue or organ keyword in the search box and hit “SEARCH”

(or use one of these examples: )
brain skin ovary eye kidney heart
liver colon muscle viscera intestine
bone testis lung blood thyroid breast
nerve pancreas spleen ear fat artery
Wait until the search is complete
When the list comes up on the page, chose ONE of the Catalog numbers (CAT#).
A page should pop up describing the gene and its source. Read it! It’s kinda cool seeing where they got this gene from!
To see the whole gene, click in the box and PICK one of the THC numbers. Then click DISPLAY THC. The page should now show a list of DNA bases that are found in the gene you searched for!
PRINT just the LIST of DNA letters (all of them). Now, translate the mRNA and the Amino Acid sequence for this entire gene. Write this on a sheet of paper and turn it in WITH YOUR COMPUTER PRINT OUT of the GENE!
INCLUDE: information about the gene: source, pathology, sex, type of tissue (specific) anything you can find out about your particular gene.
Include this information on the print out.

HINT: If you click on different THC numbers you may find a “short” gene that doesn’t take as long to translate!!

Here's our lab on the sugar production (and therefore starch production)in a leaf.
We covered parts of the leaves with foil shapes (to block out the sun).
Then we kept the plants in the dark for two days so they would stop producing new sugar and use up any sugar they stored as starch.
After two days, we put them under a plant light and let them do photosynthesis.

Our hypothesis was that the areas of the leaves that were exposed to light would produce sugar and therefore store starch! And the covered areas (in the dark) would NOT. This would mean that the cells in the light would be full of starch over the course of two days and the dark ares would have NO starch.

Since we already knew that iodine would stain starch BLACK we tested the leaves by dipping them into iodine.
The areas exposed to light turned BLACK in the iodine! and the areas that were covered stayed the light orangy-brown of iodine liquid.
Here are our results!
Our control leaf - Stayed in light the whole time and therefore turned completely BLACK!
Our experimental leaves:a big heart!

A big "T"

Another big heart.

This is an example of a good drawing,  even though I took off for not having a TITLE.

Here is  how you set up your observational microscope lab in your notebook.

I did not draw accurate pictures,  because I didn't want you to simply copy my drawings!
You need to draw your own!  

Today we did a lab on cells and tissues.

We used the light microscopes and made two different kinds of slides:
an epidermal peel of a cottonwood leaf  (Populus deltoides)
a wet mount of the leaf of an aquarium plant (Anacharis)




We drew pictures of the cells under high power and this is what we saw:  (slides below were made by Phu N.  4th period,   photos were taken with Mrs. La Bruyere's way-cool digital microscope camera.)
Cells below:  Anacharis leaf




Great job Phu!   These slides look great!

Today, we scraped our cheeks (the insides) and looked at our OWN cells!

How cool is that?

We will post some pictures tomorrow!

Enzyme lab!    It was stinky.  But cool.  
Does that make me a dork?
Oh well.   What do I care what people think!
It WAS cool!

Whoa!
We dissected the frog this week and a couple of guys in third period found an ENTIRE CRAYFISH in the stomach of their "patient".
CRAZY!
Well,  if you don't believe it,  here it is.

Isn't that amazing???
