Chromosomes, Genes, Alleles and Mutations

Chromosomes, Genes and Alleles:

Here’s a YouTube clip:

Let’s start with a tour of the basics from Learn.Genetics at Utah.

DNA coiling on histone proteins from biostudio.com

A description of chromosomes from Dexter Pratt

Zooming in to Chromosome 11 (a bit too advanced) from the DNA Learning Centre’s Gene Almanac

Transcription Java game from thinkquest.org
Mutations:

How do mutations occur? from the DNAi at the Dolan DNA Learning Centre

Evolution of Sickle Cell: Resistance to Malaria

Sickle Cell Anemia: A Mutation Story from the excellent Evolution Library.

Human Genome Project

First stop, the official website from the National Institute of Health

Here’s a great interactive from DNAi at the Dolan DNA Learning Centre

Now for some videos:

Mickey-Mouse introduction, bit of review on transcription and translation:….

If you have a spare hour (I don’t), here’s Charlie Rose interviewing Dr. J. Craig Venter:

Here’s James Watson (famous for co-discovering the structure of DNA and the first person to receive their own personal genome) chatting with NewScientist:

And don’t forget Learn.Genetics excellent site.

Barenaked Ladies – History of Everything

Thanks to HezWad from the TES Boards for this one:

Go over to the original post at YouTube for the lyrics.

The Simpsons’ take on evolution is after the jump, thanks to cb23.

Queen – Say It’s Not True

This one passed me by, being out of the country, but I found out more when I read that Queen were writing a new album and going on tour.

Why is this important?

Well, it’s Queen and it’s a HIV campaign video for a start. And we all know two things:

1. You can’t be a proper scientist if you don’t like Queen.

2. Erm… that’s it.

Let’s also not forget that not many geek-books come with their own trailers

Functions of the Liver

Here’s the powerpoint:

Download it here: functions-of-the-liver.ppt

Boring introduction (sounds like it’s narrated by Hannibal Lecter):

Introduction to liver functions from Encyclopedia Britannica

Flashy introduction, then focuses on liver cancer from the CancerCompass.com

Good tutorial with simple animation of bile secretion from Colorado State

Great EM images from Dr. Jastrow’s EM Atlas

Good histology set of specialized cells of the GI system from siumed

Absorption of Digested Food Molecules

Download it here:  absorption-of-digested-foods.ppt

Virtual Fetal Pig dissection (digestive system) from Whitman

Zooming in – Intestine to epithelial cells (with comedy Lancashire accent) from UCLan’s Sonic Nursing project

Lots of digestion and absorption animations from Nutrition.jbpub.com

Absorption of monosaccharides (tutorial) from Colorado StateNew-Yorkers in search of poo-phoria (from Salon.com)

JD and Turk telling us how poo is used for diagnosis:

Digestion (Further Human Physiology) Linklist

Download it here: digestionfhp.ppt

Let’s start with the basics:

Simple Digestion animation by kitses.com

And don’t forget the excellent review materials at Click4Biology.

Fetal pig digestive system virtual dissection from Whitman College

Control of digestive juice secretion:

Straight to the Point McGraw Hill (their page on types of glands is also very helpful)

Gastric acid production by parietal cells (advanced – look at ‘normal’ only) – John Hopkins

Another Gastric acid animation (over-detailed) PPIKnow Pharmacology website

Digestion of lipids:

Good animation from Wiley.com

Control of bile secretion (advanced) from ZeroBio.com

I’m still looking for animations for the other subtopics. If you find any, let me know!

Harvard University: list of databases online

As part of the ICT requirements of IB DP Biology, you are required to access and work with a database of biological information. The department of Molecular and Cell Biology at Harvard (which is well worth spending some time looking though) has posted this extensive collection of links.

Children’s Hospital Boston – Great Flash apps for students

Thanks to Rod Murphy for this one.

eSchool News featured CHB’s site as site of the week and it’s well deserved. There are some great animations here, including a nice neurons and synapses animation, some stem cell resources, cancer information and a chance to have a go at making an EM image.

Go have a look!

Jellinek – Drugs and the Brain

Thanks to Roger Allison for pointing out this one.

Jellinek is a Dutch drugs education website that has some great, accessible resources for neurobiology of drugs and the brain. Animations are available in multiple languages.

For more details on the brain, neurobiology and behaviour, see the DP Bio Linklist.
